I think that there are many others that feel the same way you do. At your age and older; I know. I went through that when I was your age. I lived at a dorm when I went to college and it seemed just like everyone else was "doing it". I remembered how bad I really felt.

I think that later on your life, you may be surprised on how you feel can turn around. It has happened for me.

If it can be of any help, I go on another forum board called "Web of Loneliness". I don't know if you have heard about it. With that, there is a Twitter section called "Forever Alone". Pretty interesting stuff.

Just one little bit of advice of what I saw that you put down, though. Be careful about tanning. Over the years in my life, I felt like I got a lot of sun exposure. I've had some skin cancer surgeries (three in the last six years). They were minor, but they are a hassle to go through. I think that tanning at a salon may be more risky than getting sun exposure.
