Rejection therapy and getting rejected

im hoping to get advice. im not losing sleep over it but it keeps finding its way back in my mind. about a week ago i got rejected and ignored several times, generally just had to approach so many people while i was looking for an apartment and a good college to get into. i thought, since ill go through more rejection looking for a job soon, i might as well just go all in and made a rule to add everyone i knew on facebook. essentially if i recognized their face, i added them.

as you’d guess and as was my intention several people didn’t accept my request. but i didn’t expect some people i thought i was cool with to reject my request. i do feel like a loser im not gonna lie. i know its a lesson ill have to learn eventually that not everyone will like me and that its all good, but i was hoping if there was anyway to make this feel. idk. less sh!tty.

sorry if this post sounds stupid. it has just been weighing on me and idk how to deal with it.
