any 18 year olds feeling the same way?

i graduated highschool and i go to a college that is online. looking at other 18 year olds and their life at college and having the best time is seriously breaking me. my mental health has worsened by the time school started and just seeing college freshmen having like the best time of their life at college is getting to me. i wish i had the “college experience” you know like living in dorms, being in a new environment, meeting new people, and everything like that. i literally just stay at home all day and it sucks. i dont have a social life or anything. i wish i went to a 4-year college. it’s bad that i literally cry to this every single night. like we’re still so young and not being able to make fun memories and living in the time period where ppl say this is your best 4 years just hurts. i know im going to look back at this when im older and can’t help to think why didnt i just go to university???? i wasted my youth for what?? is there any 18 year olds feeling this way?
