Will this insomnia ever go away?

I've been having trouble sleeping for a few months now. I tried sleeping pills but they don't seem to help. It actually makes it worse because, when I finally do go to sleep I will sleep until 11:00 or 12:00. I've even tried just laying in bed until I go to sleep, but I will literally lay there for hours before falling to sleep around my usual time wich is 3:00 or 4:00 in the morning. I don't know what's wrong with me. I feel so hopeless sometimes, but not all the time. Then again I feel wonderful and happy sometimes. I will soon have to start working again because of the rising prices on everything. I wish I didn't have to. I get to emotionaly involved when I work. I think that's stressing me out as well. I don't want a job that's the same routine every single day, it drives me crazy. However I don't want a job that has no purpose. Maybe I put that wrong. I want to do something that is working toward a good cause, something meaningful. My dogs will have to stay home alone. I hate that, I enjoy being with them so much I can't stand to think about not spending as much time with them. I looked for a job that I could do at home but everything seems to be some kind of pyramid scam! I wish I could go back in time and be a kid again just for one whole day.
