Insomnia Again

I never had insomnia for awhile not until these past few nights. Have had trouble going to sleep and no matter how i tried to close my eyes, my mind is everywhere and thinking a lot of things. I don't know why, i can't seem to sleep very easy, i am even scared to take sleeping pills because i heard some bad effect of it. I really need a full rest but i don't think i can get it since i wake up early in the morning to take care of my two kids. I started to look awful now for having this deark circles under eyes. I really want to get rid of this because it makes me look older and groggy. My eyes looks so sleep all the time every time i look at myself in the mirror, just ugly circles under my eyes, i am not happy looking at it.
