Didn't see your thread in newcomers but it caught my eye here.
Definitely, work on those things you mentioned about the clutter and the make-up lesson. Anything that makes you feel good about you and boosts your self esteem.
Did you go to the MC session yet? If not, try to keep an open mind and not go in there with what you know.
Other than that, I would say in regards to your H, be agreeable, friendly, you say you have been low maintenance well, start a 180 there and do some high maintenance things. Grow your hair get some different clothes and shoes. You say funds are low so start slow.
For you, go and do some things you may not normally do. What is something you have always been interested in but didn't get the chance to do?
Also, as SG suggested seek out your neighbours and other friends. My one neighbour was great when my H first left me. Invited me to dinner and her parties, over for a glass of wine, etc.
My big thing in the begging was to make a goal list. Big and small goals broken down into doable tasks. That helped me to focus on something.
The giddiness your H feels now will pas, it always does so just bide your time. I know it's hard but it helps to stay busy.
Make up your GAL list, follow it and add things as you think of them.
