srsly what is wrong with me

lately i haven't been feeling like myself, i feel so alone even tho i'm surrounded with people, i keep confusing reality with my daydreams. I really feel like i have gotten to used to imagining myself in a different world, different face, different friends, and a different family. I really don't know anymore, i have a good family, my face is okay i guess, but maybe it's the friends part. A certain friend of mine made me lose my trust in most of my friends because they said that they never liked me in the first place even tho i was always there for them when they needed me, and i never asked for anything in return. I can barely trust any of my friends now, it always feels like they're talking behind my back.
