How are you supposed to deal with constant and persistent rejection?

I usually look for guy on various apps and social networks since I'm not really into the scene and those things make it so much easier.Now I know I'm a pretty unattractive guy which makes it very hard for me being very into stereotypical my attractive guys. I know I'm out of their League but I try anyway. Like you would expect I almost never hear back from anyone. I just get ignored or blocked outright. This has been going on for some many years I've just given up and removed all these networks off my phone. I don't even try anymore. How to you guys deal with constant and soul crushing rejection?
