I have had insomnia for about 20 months. i had sever anxiety and depression because of it. i was so ill with candida i felt my life was over. I have learned so many lessons this past year. the biggest one is my fear. I overcame it by facing it. i havent had a anti depressant since last January. I havent had a panic attack since christmas. My insomnia was so bad last year but i now know it was aggravated by fear. The more i fretted the less i slept. at one point my family wanted me certified! i was a wreck. if you knew me you would be amazed how far i have come on.
you obviously are going through a similar thing to me, you seem anxious about the lack of sleep . well through my own experience im telling you you wont die, you wont go mad, you can get through this. be strong and know you are not alone.
Also try the sleep restriction therapy its pretty good sometimes. go to bed 2am to 8am and do not sleep at all in the day, try this for 2 weeks, its supposed to train your subconscious into associtating bed with sleep and you get so tired you actually sleep better at night. Im doing this and it works ok with me usually. but most of all stop worrying because once you master that the fear of insomnia loses its grip and you find you can sleep better in the end x

I will try the sleep restriction therapy, thank you for your support and help, it really made me feel better.
