Trouble sleeping, waking in panic, palpitations more intense.

So, recently, I've been having some trouble sleeping. It's like I'm afraid to fall asleep for fear of waking in panic or not waking at all :( even when I'm so exhausted I could sleep on the floor, I go lay down ready for bed and I just can't fall asleep. I've been having more intense and frequent PAC's and I've had about two anxiety attacks in the past week. (I had been doing good, like maybe one every 2 weeks). I awoke just recently in a panic. I felt lightheaded, weak, dizzy, out of breath, and like my heart was struggling to beat and thumping hard. I feel just helpless. I tried breathing exercises and drinking cold water and that seemed to help but now I am worried, because all of a sudden my PAC's are more intense and happening more frequently and I' m also having trouble sleeping. Wondering if I should make a trio to my general physician. I was feeling fine before, until I started having trouble sleeping. It's so exhausting being an excessive worrier. And I can't help it either. All I think about is being a mom to my son. I don't want anything to happen to me for sake of Cameron. I don't want him to be without a mommy and i don't know why I have to experience all of this at such a young age. I am trying SO hard to overcome and adapt to this without medications and ibolan to keep it that way. If anybody has any suggestions or input or any positive thoughts at all, please help! I just need to talk :(
