The insomnia could well be because of your depression, medication or both.
Do your family help you in any way? Would you feel comfortable asking a member of your family to go through some things with you (take some pressure off). Even if it's just so you have some support there while you sit and make a list of priorities that you need to do. Thinking about all our troubles at once only worsens the situation, so breaking your tasks up into priorities may help?
I'm glad you'll be able to see your T again soon and it might be an idea to print some of your posts off to show him/her?

Take care and stay safe
