i was in my 20's, it is harder to find friends in the real world, not high school or college. i think you are around kids at your age.
you live college campus, you have roommates. you make friends and you have classes, you make friends that way.
when you live on your own in own apartment, or whattever, you by yourself. maybe, roommates or girlfriend or boy friend. you have friends.
i lived with my mom until i was 28, it got the point, that honeymoon was over. my sibling, or at least, my brother told me that living with my mom. it was being a marriage. my mom and i were old marriage couple, we fight a lot and we had our good time and bad times. it got to the point that i had living my own apartment.
i can relate what the op is feeling, you have nobody to hang out with. in time, you make friends.
with me, i like living on my own, i had friends since i lived on my own. i found it easy to not to have friends over that much to my apartment. i like beingby myself, not to have talk to people all the time.
occasionally, i see one of my friends in public and said " hello" to them. maybe, get together for a lunch or dinner, or something. but that about it, i found that i am like be on my own, more than have company over the years.
i have admit in my 20's and 30's, it was rough for me to accept that i want friends. also, i admit to myself, that it is ok to be alone. i didn't be shame of it.
i'll be 60 in november, this first time that i am content with my life. i like being alone. that i have go out my way to make a friend, just because i am alone.
in may way in my life for years, i didn't like myself. now, i like myself. i am happy!
