For me its the exact opposite of what most people here say.
It doesnt get better. It gets worse. I felt pretty content during my 20s bc life got better, I had more freedom and my own money. But starting with 30 all you missed out on starts to hit hard. I used to not care, now I cant think of anything else. Bc its too late. Its over, really. Everything I should have done should have happened 10 years ago. Now I will never be able to catch up. That fantasy of finally meeting nice people who will accept you didnt come true. With 30+ you are the creepy old dude who doesnt really belong anywhere, if you havent established yourself with others already.
Lost time is never found again. Remember that anon. Ive heared that sentence too late.

i literally have no muscle mass. 21 year old male, and i have no muscles. just flesh. is this what 21 years of piss poor nutrition does to you?
