What about volunteering at a library just to get started. Not a lot of contact with people but still gets you out of the house. You could ask if they need help in the used book store, stacking shelves, etc. You remind me so much of myself as a young woman. Oh I still have issues but they're different as you age. There is only one answer and it's not easy but simple. You have to do the thing you fear in order to get over it. Try to think beyond your nervousness and what others think of you, decide what you want out of life and what you need to do to get it. The heck with everyone else who you might feel are judging you (they're probably not anyways). Most folks are solely wrapped up in their own lives and problems.

I wish you the very best, you're such a sweet person just overly sensitive like so many of us. I could tell you a lot about my youth and how I overcame my low self-worth and lack of confidence, but there isn't that much room here, LOL. Like I said the answer is simple, the work is hard. But I know you will make it. If I did, I know you can.
