Sleep, as you well know, is so important that we need to get at least an average of 7 hours a night. You, obviously, are not getting nearly enough and the lack of sleep begins a vicious cycle of anxiety that can only make your panic worse. So sleep is extremely important for you right now.
I know this is something you already know, but I just wanted to let you know that the reason you may be having more problems now is that the cycle has begun and it has to be broken.
I am not an M.D., and I do not recommend anything OTC, but I do know that there are things that may be helpful to you. On my website I have a Sleep page that has links to resources that will provide information on sleep to you. One of the things that they do recommend is that you abide by what is known as "sleep hygiene." By that they mean a number of things that will contribute to your getting better quality sleep. I know, in your case, this means getting more sleep than you have been getting recently. Please take a look at what they are recommending.
Sleep medications are not something that should be taken lightly and are generally only taken for short periods of time because they can present problems when taken on a regular basis. I am not, therefore, indicating that this would be something for you to consider.
Lifestyle changes, too, are something that needs to be considered because what you do during the day affects how you will be able to or not be able to go to sleep at night. Stress reduction, of course, is something that must be considered and one thing that you can do regarding this is simple, regular mild to moderate exercise. Of course, you should check with your physician because you need to know whether or not there are any medical conditions that could be causing your current sleep difficulty.
Also, please take a look at our Tips column, watch the relaxation breathing video tutorial and begin to use that exercise on a regular basis.
I hope things do improve for you shortly and that you do begin to get the sleep that you need.
