Can't sleep and really freaking out about it

So ever since 2008 when I started having panic attacks I've struggled with sleep. My whole life I've had trouble falling asleep. Even as a kid it would take me an hour or more of laying in bed thinking/day dreaming until I would finally fall asleep at some point. But in 2008 with panic added onto it, it's made it ten times worse. I'm not just laying in bed with my thoughts, but with anxious/panic thoughts. And then when I finally fall asleep around sunrise, I sleep all day and ruin my sleep schedule. Then I have to stay up all night and all the next day to get back on a schedule. Here's where the big problem comes in. The longer I'm up, the harder it seems to sleep. I get this weird feeling in my head and chest that makes me feel really weird and not tired even if I really am exhausted. So when I have to stay up that long to get on a normal schedule, it's even harder than usual to sleep and feels like I never will. This is what I'm dealing with right now. I've been up since 5 PM the day before yesterday. I had a two hour nap and that's it. it's 4 AM and I had been laying in bed since 10 PM before I got on to write this. I lay in bed for hours and nothing happens in my brain. It's like it just won't go to the point of sleep. I can't even feel it going anywhere NEAR sleep. I'm just laying there wide awake even though I've been up 30 hours or so and am exhausted. On a night when I can sleep, the longer I lay in bed I can feel my brain slowly going into sleep. But on a night like this, I feel NOTHING. It goes nowhere. I even took a Xanax and that didn't work. I've also tried Benadryl, Tylenol PM, Motrin PM, Goodys PM.. none of them do anything. So I just get this panic about what if I never can sleep? It's never been this hard before and I'm freaking out. What if I'm up 3 days, 4 days, 5 days... and if it's harder to sleep the longer I'm up, how will I ever fall asleep now or after that ammount of time? I'm really terrified. And no, that's not what's keeping me up. I'm able to control that anxiety and those thoughts while I'm laying in bed and clear my head. I just don't know what to do and I'm miserable. I have panic attacks and anxiety about not being able to sleep because I'm scared this will keep me up for days and I'll start hallucinating or something.

I feel like I've really tried everything and don't know what anyone could possibly tell me that I haven't done.. but I'm desperate. I've tried reading, meditating, progressive muscle relaxation... My room is completely dark and quiet, etc. All the things you're supposed to do, I've done.. I don't know

Oh I am in your position too!! For me I was stressed that I wasn't going to get everything organized in my apartment in time for my driving lessons in July. I was even crying. Then I took a shower and still cried. What I did next was listen to my Progressive Muscle Relaxation CD. I'll be back later with the author's name in case you want to get it, and that CD does wonders. I've had it for years and have never been disappointed. It's like the same as an anxiety pill or even better if you dso it often enough. It took away my worries about getting stuff done but still, I don't feel that sleepy so I can't get to sleep right now either. It's 4:17 am. I am groggy though. I really think it's because the pills I'm on for sleep aren't working anymore. Not even an Ambien did the trick after taking 2 Trazzodones. I used to be able to get to bed around 1 or 2 am just this year too! So I gotta talk to my doctor about this and it will have to be my family care doctor because it will be May 31st before I see the new psych. BTW, I am not crazy or anything - just have sleep and hoarding problems. I would appreciate any kind advice. Thank you. And good luck to the OP.
