Struggling with the Direction

Sunday night I had a really bad night, to the extent that I started looking up suicide webpages, I had been helped earlier in the evening by to good friends, but later on my head took off again. This has been going on for several months now with me no longer feeling that I knew the direction to go in order to get out of the current bout of depression. Now reached Wednesday and the thoughts have been increasing, it is tiring to be constantly fighting the urge not to cut my arms, feeling so tired yet my insomnia is in full flood. I am trying hard to hold onto the people who helped me on Sunday when I asked for help.
