I have a group of "friends", but l'm never anyone's first choice to be around. I'll ask to hangout, and they say no, and even bail on me even on the rare occasion they ask me to hang out. But then, when one of them is feeling left out by the others, they'll reach out to me. Sometimes it feels like they only want to be around me when they need their "girl gang" instagram post. I'm the backup friend. But I know that if I assert more boundaries, and tell them how I feel, I'll lose what little social interaction I have. I'm a full grown adult with no idea how to make friends, and I'm afraid I'll never have a close friend connection again. - Human
