Teenage Angst at 21?!?

I've recently been experiencing depression and social anxiety and moratorium so much so that I've been out of work and reclusive for the past two years. I had a lot of issues in my childhood and was forced to "grow up" and be an adult at a very young age. I am currently in counseling and I'm on anxiety medication. I'm on the verge of turning 21 and I'm at a point in my life where I'm safe, secure, could this depression and anxiety be a result of me experiencing the teenage angst that I was deprived of? Has anyone else had a similar experience and can relate to how I'm feeling? I'd appreciate any feedback and advice.
