Today I turned 23 and felt happy at first but now I'm evaluating my life and feel like I haven't accomplished enough. I feel like there's pressure to go out with friends (which I don't have any) and like I should've dated by now (never had a boyfriend). I have some social anxiety and really don't socialize with anyone. Not to mention I'm in last year of college so definitely feel left out.

How can I not feel bad about celebrating alone?
