Think of a shrink as a better version of what you've already done in asking for help. He's an pretty smart guy(hopefully) who you can tell shit to that you would never tell anyone else. And he'll give you an honest 3rd party perspective, which is exactly what you need. You need someone to tell you that it's not as bad as you think it is. You need someone to tell you that the way you are seeing yourself is complete bullshit. You need someone to help you figure out what actions are going to make you start feeling good about yourself and encouraging you to do them.
