I am 25(M) and never even touched hand of opposite sex, at this point i am kinda sure that im going to be alone in my life, but i just cant get over it. I am ugly and skinny, and as for recent started going bald. Have some heart issues so no heavy physical work. I have no chance. So i wanted to move on from this state of mind, and just focus on work and hobbies. How can i do so? Do you have any advice you can share?

I (23M) was sitting on a bench drawing and a girl sat on the same bench, then she started talking about my drawings, I said a few words about them, but I started to feel that I was getting very nervous, and after some phrases i just stood up and walked away to another part of the park. A few minutes later I saw her heading my way again. But when she saw me her face became sad and she turned around and walked back the other way. Now i feel so awful about all this ,I didn't mean for this to happen but it kinda did. I want to ask people any advice of how to overcome this fears so this is not happened again. For the context i didnt have any genuine converstation with girls in 8-9 years, and i didnt have this problem with males
