I need someone to talk to

I want to ask for someone to talk to or to ask to vent but I feel like it's cringe. I wish I had someone to have litsen to my problems.

My grandma saw the scars on my arm and she keeps threatening to tell my mom.

Everything is always my fault, my mom and her boyfriend arguing, my mom and her mom arguing, every single problem in my life is my fault. All of it. Every single bit of it is my fault.

I hate everything. I wish I had someone to hold me and tell me it isn't my fault. I wish I had someone to support me when I need them. I need someone. Anybody. Please.
