So I'm 17 and feel as though i'm going insane. My family foesnt understand and i feel like they believe im going crazy as well. From the time i wake up to the time i go to bed i think and firmly believe im dying. Insane right? I always worry that i have diseases or am sick ir have a fatal disease such as cancer. Every ache and hurt in my body i immediately think im dying. I can barely sleep anymore, im always awake with chest pain, shortness of breath and a fast heart. I work myself up for no reason. On top of that im always crying and upset for no reason at all. I'm always sad which makes me think why live if im living like this. This is not living. Whatever this is holds me back from everything. Its currently 2:41 and i cant sleep and im up worrying about everything. Tomorrow i have a CT scan for constant migraines and head pains which for some reason i convinced myself its a brain tumor =( why? I dint know. Honestly i think im going nuts, and i dont kniw what to do anymore or if i wanna do it anymore.
