体調 means physical condition, state of health, or how your body is feeling.

In this sentence, it refers to the speaker’s health not being back to normal yet.

It is a little more specific than:

• 気分 = mood / how you feel emotionally, or sometimes how you feel physically in a vaguer way
• 健康 = health in a broader, more general sense

So 体調がまだ戻っていない means something like my physical condition still hasn’t returned to normal.

Here, が marks 体調 as the thing being described by the predicate まだ戻っていない.

So:

• 体調が戻る = one’s physical condition returns / recovers

This is a very common pattern in Japanese:

• 体調がいい = my condition is good
• 熱がある = I have a fever
• 頭が痛い = my head hurts

Even though English often uses I as the subject, Japanese often puts the body condition itself as the grammatical subject.

With a negative verb, まだ means not yet.

So:

• まだ戻っていない = has not returned yet

This is a very common pairing:

• まだ食べていない = haven’t eaten yet
• まだ終わっていない = hasn’t finished yet

If the sentence were positive, まだ could mean still:

• まだ雨が降っている = it is still raining

戻っていない is the negative of 戻っている, and here it expresses a current ongoing state: the condition has not yet returned to normal.

So the nuance is:

• 戻らない = does not return / won’t return
• 戻っていない = has not returned yet

In this sentence, 戻っていない fits better because the speaker is talking about their present condition as of now.

It sounds natural to say:

• 体調がまだ戻っていない = my health still hasn’t recovered

ので means because or so.

In this sentence:

• 体調がまだ戻っていないので = because my condition hasn’t recovered yet

Compared with から, ので usually sounds:

• a little softer
• a little more explanatory
• a little more polite or less direct

So:

• 〜から = because... / more direct
• 〜ので = because... / gentler, more explanatory

Both would be grammatically possible here, but ので sounds very natural when calmly explaining a reason.

は marks 明日 as the topic or time frame being focused on.

So:

• 明日は = as for tomorrow / tomorrow

This often gives a slight sense of contrast too, like:

• at least for tomorrow
• regarding tomorrow

It does not necessarily mean strong contrast, but it helps frame what the decision is about.

In Japanese, subjects and possessors are often omitted when they are obvious from context.

Here, 体調がまだ戻っていない is naturally understood as referring to the speaker:

• My condition hasn’t recovered yet

That is because the next part, 母に家に来てもらうことにしました, is clearly about the speaker’s decision.

So Japanese does not need to say 私の体調 unless there is a reason to emphasize it.

This means:

• to have my mother come to the house
• to ask my mother to come over
• to receive the favor of my mother coming

The key grammar is 〜て もらう.

• 来て = come
• もらう = receive

So literally, it is something like:

• to receive my mother’s coming to the house

In natural English, that becomes:

• have my mother come over
• ask my mother to come over

It implies that the mother’s action benefits the speaker.

They do different jobs:

• 母に = from my mother / by my mother
  This marks the person who does the action in the 〜てもらう pattern.
• 家に = to the house
  This marks the destination of 来る.

So:

• 母に = my mother is the one I’m getting to do the favor
• 家に = the place she is coming to

Even though both use に, their functions are different.

This is an important nuance difference.

• 母が家に来る = my mother comes to the house
• 母に家に来てもらう = I have my mother come to the house / I ask my mother to come over for my benefit

〜てもらう adds the idea that the speaker is receiving a favor from someone’s action.

So in this sentence, the speaker is not just stating a fact about the mother coming. The speaker is saying that they decided to arrange for their mother to come and help them.

ことにしました means decided to.

The pattern is:

• dictionary form / verb phrase + ことにする = decide to do something
• past polite: ことにしました = decided to do something

So:

• 来てもらうことにしました = decided to have someone come / decided to ask someone to come

This pattern turns an action into a thing / matter with こと, and then says that a decision was made about it.

Because する by itself would need a direct object that clearly says what was done.

Here, the whole action 母に家に来てもらう is being treated as the thing decided on:

• 母に家に来てもらうこと = the matter of having my mother come to the house

Then:

• 〜ことにしました = decided on doing that

This is a fixed and very common structure in Japanese.

しました is the polite past form.

So:

• ことにした = casual
• ことにしました = polite

The sentence is simply using polite style overall. It does not change the basic meaning; it just makes the sentence more polite.

When talking about your own mother to someone else, Japanese normally uses:

• 母 = my mother

When addressing your mother directly, or sometimes when talking about someone else’s mother, you often use:

• お母さん

So here, because the speaker is referring to their own mother in a neutral way, 母 is the natural choice.

Yes, here 家に来て means come to the house, and in context it usually means come to my house / our house.

Japanese uses 来る from the speaker’s point of view, just like English uses come when the movement is toward the speaker’s location.

So because the mother is coming to where the speaker is, 来る is correct.

Yes, it could.

• 家に来て = come to the house / come home
• うちに来て = come to my place / come over

うち often sounds a bit more conversational and personal. 家 is perfectly natural too.

The exact nuance depends on the speaker, region, and situation, but both can work.

The sentence sounds like a calm explanation of a practical decision:

• the speaker’s condition still has not recovered
• because of that, they decided to ask their mother to come over tomorrow

Important nuances include:

• まだ戻っていない = recovery is incomplete
• ので = soft explanation of the reason
• 〜てもらう = the mother’s coming is helpful to the speaker
• ことにしました = the speaker has made that decision

So it does not sound dramatic. It sounds matter-of-fact and natural.
