I've been going through a lot recently. Both my school life social life and my self image has gotten incredibly worse and I started noticing when I cry a lot or feel a deep sense of pain I get this feeling like theres a knot in my stomach but it feels so good for some reason. Mentally I feel so bad I'm scared, sad and angry towards myself and everyone but physically it feels so good for some reason. (I also don't know what or who I trust and I can't trust literally anyone including myself and that leaves me feeling lost thats why I feel scared) Is this normal? Should I see a therapist?
