Suggest Treatment For Difficulty In Getting Proper Sleep

Hi i have a question about restyl . I had and it from friend for long time i k(now is not good thing) as I have had sleeping problems but never used till i had one of those really stressful times in you life which shake you all you brain ...anyway I ve been thanking it for a while as I need some sleep but even with one and half tablet 0.25mg its been difficult for me to get sleep... also i had some panic attacks in my past very bad and now I had few not that strong . My GP did not help me a lot when i told her for panic attacks (as they couldn t find what was wrong with me )just gave me some regular tablet for high blood pressure. Im feeling again im out of control and totally lost what should I do because most of doctors don t take it very serious just give you some quick medicine as I never bring my problem to the doctor just dont want look one of those crazy people even for panic attacks i realized what it was after 4-5 years..... However I just wanna know what is the best suggestion for my sleeping problem and how can I solve my problem with stressed . Its not some regular thing as Im just 25 and my first panick atacks ware I was 19-20 years old ... Many thanks
