Is it normal to still be a virgin at 30 under these circumstances?

Well done to you.

I think after all you went through there should be no issue in getting a girlfriend.

Stop telling yourself all the negative things. I mean, look at where you are now.

You are saying that after all the hard work you went through to get out of the wheel chair, that you cannot approach a girl.

Snap out of it! It is that much easier now. Who cares if you get embarrassed? It happens. And trust me, she will not care if you get red in the face or confuse yourself whilst talking to her.

The right girl will not judge you, and will let you approach her and take things further.

Get out of the house, look around;if you happen see the one that you like, say hi, introduce yourself. If that does not work, find another one. There are so many girls out there.
