I can’t out of my head

I’m so in my head lately. I eat pretty much once a day but not cause i’m trying not to i’m just never hungry anymore. I don’t do anything all day unless I have school but other than that i’m alone in my room all day. I can’t seem to get out of my head. I’m scared of what people think about me constantly and I wish I just didn’t care. I don’t want to die but I just am so bored with my life and I don’t know what to do. Even when I do go out of the house I only have 3 friends and we pretty much do the same thing every weekend.
