You have so much going on - I think what you're feeling is absolutely normal. It sounds like you took a great first step to be a healthier happy person, and to provide the best for your daughter.
You sound overwhelmed, and I can certainly understand why.
But...if you can.... try not to think of everything at once. Use the supports you have (your T, group and boss, and other family??) and it will eventually all fall into place.
And keep posting here so we can support you too.

With care,
