Feeling a little low

Maybe it’s just hormones.. idk, but I’m feeling pretty low rn. I feel like i honestly have no one, growing up i always had one close best friend that was like a sister to me & i kinda grew out of them all, I’m starting to see people for who they really are and i just rather not have them apart of my life. A friend i had for 12 years actually i stopped communicating with. I let her live with me for a bit and i just saw who she really was. Jealous, passive aggressive and really weird.. she texts me off and on but I’m just truly not interested. Id say i have more acquaintances then actual friends. I consider a friend who i can call when I’m happy or sad and they’re there for. Genuinely. These “friends” i can’t really trust and that’s why i don’t call them friends. Idk it just sucks because i don’t feel it with my SO either.. ☹️ and my mom was never really there.. so i tell myself i rather be alone then be around people who aren’t genuinely happy for me but i still feel so alone right now and feel like i truly have no one there for me. Idk just needed to vent
