Η σύντροφός μου με βοηθάει να κρατάω την ψυχραιμία μου όταν έχω άγχος.

Because βοηθάω / βοηθώ takes the person being helped as a direct object in Modern Greek:

• βοηθάω κάποιον = I help someone

So:

• με = me in the accusative
• μου = to me / my in the genitive

That is why με βοηθάει means she helps me, not μου βοηθάει.

Modern Greek does not normally use an infinitive like English to keep. Instead, it usually uses να + verb.

So:

• να κρατάω = literally something like that I keep
• but in natural English it corresponds to to keep

In this sentence:

• με βοηθάει να κρατάω... = helps me keep...

This is one of the most important patterns in Greek:
instead of an infinitive, you often get να plus a finite verb form.

Because Modern Greek has largely lost the old infinitive. Where English says:

• to keep calm
• to go
• to eat

Greek usually says:

• να κρατάω
• να πάω
• να φάω

So κρατάω here is not an infinitive. It is a verb form used after να.

This is about aspect, which is very important in Greek.

• να κρατάω = imperfective aspect
  suggests an ongoing, repeated, or general action
• να κρατήσω = perfective aspect
  suggests a single, complete action

In this sentence, the meaning is general/habitual:

• My partner helps me keep my cool when I’m stressed/anxious

So να κρατάω fits well, because it means something like:

• to keep staying calm
• to maintain my composure

If you used να κρατήσω, it would sound more like helping in one particular instance.

In Greek, possessive pronouns like μου (my) usually come after the noun:

• η σύντροφός μου = my partner
• η ψυχραιμία μου = my calm / my composure

This is completely normal Greek word order.

So Greek often works like:

• the partner my
• the calm my

even though English puts my before the noun.

Because it modifies two different things:

1. Η σύντροφός μου = my partner
2. την ψυχραιμία μου = my composure / my cool

So each μου belongs to its own noun.

They do not mean the same thing syntactically, even though both are translated as my.

This happens because μου is an enclitic word, and Greek spelling sometimes adds an extra written accent to the word before an enclitic.

Base form:

• η σύντροφος

But when followed by enclitic μου, it becomes:

• η σύντροφός μου

This extra accent helps show the correct stress pattern in pronunciation.

So this is not a different word or case; it is the normal noun σύντροφος plus the possessive μου.

Σύντροφος can mean companion, partner, or in some contexts even comrade. In everyday modern usage, very often it means a romantic partner.

So here:

• Η σύντροφός μου = my partner

It is less specific than wife or girlfriend unless the context makes that clear.

Yes. Both are possible.

• βοηθάει
• βοηθά

Both mean he/she helps.

The longer form -άει is very common in everyday speech and writing. The shorter form is also standard.

So these are both acceptable:

• με βοηθάει να κρατάω...
• με βοηθά να κρατάω...

The same kind of variation happens with other verbs too.

Greek often uses the definite article where English may not focus on it as much.

Here ψυχραιμία means calmness, composure, and the phrase:

• κρατάω την ψυχραιμία μου

is a very natural Greek expression meaning:

• I keep my cool
• I keep my composure

The article την is part of this normal structure. Greek often says:

• κρατάω την ψυχραιμία μου
• literally: I keep the composure my

Even though English idiomatically says my cool or my composure, Greek naturally includes the article.

Ψυχραιμία means calmness, composure, or cool-headedness.

So:

• κρατάω την ψυχραιμία μου literally = I keep my composure
• idiomatically = I keep my cool

It is a very useful noun in Greek for talking about staying calm in difficult situations.

Greek often expresses this idea with have:

• έχω άγχος = literally I have stress/anxiety
• natural English = I’m anxious, I’m stressed, or I feel anxious

So in:

• όταν έχω άγχος

the literal meaning is when I have anxiety/stress, but a more natural English translation is often:

• when I’m anxious
• when I’m stressed

Greek and English just package the idea differently.

Because άγχος here is being used in a general, uncountable sense:

• έχω άγχος = I have stress / anxiety
• more naturally: I’m stressed / anxious

Greek often omits the article with nouns in this kind of expression, especially with abstract or general states.

So έχω άγχος is the normal way to say this.

Όταν means when.

It introduces the time clause:

• όταν έχω άγχος = when I have anxiety / when I’m anxious

So the whole structure is:

• Η σύντροφός μου με βοηθάει... = My partner helps me...
• όταν έχω άγχος = when I’m anxious

The given word order is natural, but Greek word order is more flexible than English because the endings and articles show grammatical roles.

The sentence:

• Η σύντροφός μου με βοηθάει να κρατάω την ψυχραιμία μου όταν έχω άγχος.

is a neutral, natural way to say it.

You can move parts around for emphasis, for example:

• Όταν έχω άγχος, η σύντροφός μου με βοηθάει να κρατάω την ψυχραιμία μου.

That puts more focus on when I’m anxious.

So the word order is not completely fixed, but the original version is a very normal default choice.
