I've been laying in bed daydreaming for hours after waking up, taking a shower for up to an hour, laying in bed and daydreaming or worrying/feeling bad for myself for few more hours, delaying meals (consistently eating lunch at 8, just sitting in my room while starving), taking hours to fall asleep then waking up in the middle of the night with my entire bed soaked in sweat. It severely affecting my life but Im scared of getting help. 

Ive never told anyone about this and now I've never felt worse, im shy and being so person with a stranger is embarrassing. My last doctor was awful and now I'm scared of getting rejected, told that Im just stressed or something. I feel like I won't know how to answer a lot of the questions, I don't really understand how I feel myself. And I don't know if it's even depression. It came so suddenly for no reason, Ive always had symptoms but nothing severe. Everything was working out, I became really inspired then a few days later I just couldn't do anything. Its been over a week and I have no choice but to get help. What is diagnosis like?
