Some guy, I know how you feel. This was one of the first things I told my therapist when I first started to see her. I just turned 27 this past Monday and my best friend didn't remember. Didn't do anything special and I was fine with nobody remembering because I feel like the older I get the more I fall apart, physically and emotionally. I live in an apartment with my younger brother and we share the rent that I can barely afford. I have a job but no career. I thought that I would have been married by now, possibly with kids or a baby on the way with a job I loved. My therapist asks me who made the rule that I was supposed to have all my **** together by now. I understand what she is saying but it doesn't make me feel any better.
I wish I could tell you something that made you feel better, but I hope at least you don't feel like you're alone.
