I had a breakdown about 8 years ago.
I couldn;t eat (was sick immediately I tried to eat something), couldn;t get to sleep, and would wake really early very anxious, plus several times in the night, with heart racing.
Couldn't relax, and tried to avoid any situation where I had no distraction (e.g. having a bath was hell).
Wanted someone to give me a pill so I could sleep as I was so tired all teh time but couldn;t get any rest.
Eventually when got really bad, became afraid of my thoughts (e.g. semi-suicidal) etc.
No-one realized I was depressed at first because I was having more anxiety related symptoms.
What are you experiencing right now?
