Hi and welcome back!
I can relate to a lot of which you have written.
I am struggling with some of the same issues.
Yes, I love the comfy sweat suit! I have been trying to do better and have been adding to my wardrobe a bit, though not too much because I am in the midst of losing weight.
I don't have agoraphobia, per se.
I do go places, most often, with my husband. I like spending time with him. I have to admit that although I don't feel "unsafe" without him, I feel more comfortable with him. I do go places on my own.
I'm glad to hear you are doing better.

It all takes time, and some days, lots of effort.
Hope to see you around the forum, Jensitive.
