I am afraid I am the type of person who comes here and tries to fix things. I just don't know what to say about your situation. It's so sad. I am very sorry for you. Like the others, I hope you will give reaching out to others a chance.
Perhaps you could try a support group of MSers. Nobody understands what we go through like one of our own. If you have a local MS society near you, you might give them a call and explain things. They may have support groups or even social groups that might be to your liking.
You can rebuild. Remember that for many (for me anyway) attraction has very little to do with appearances and abilities. Just get out there and be you. You received excellent advice from both Msmama and Diana. I hope it will help you'll feel better soon.
Msmama, I was touched by the fact that you registered just to reach out. Thank you!
