How do I alleviate bitterness due to lack of intimacy?

I have given up trying to find a girlfriend. Even though, I am outgoing, have hobbies (I dance, which is actually filled with women), go to parties, talk to plenty of women. But I keep hearing the same thing over and over again: "I am just not so into skinny guys."

I think this is fair from the woman's perspective. I for one am only motivated to date attractive women. So, them not wanting to settle for less actually makes very good sense to me. There is absolutely no hate or bitterness regarding that. Fuck all that: 'all women are whores'-noise.

That being said, I think I should just consider myself celibate by virtue of my own standards. But now bitterness is starting to take hold of me. Bitterness about my life and to me as a person. As I said I am very outgoing and don't want to become the cynical asshole around my friends.

So how do I stop this?

Edit: I go to the gym on a regular basis.
