So I'm feeling anxious as hell right now, shaking, nausea, weakness etc. but I'm currently so tired (it's almost 3am here) and every time I begin to nod off I keep getting that jerking awake with panic. It's happened a good 12+ times to me tonight and now I'm terrified to even try and go to sleep again. Plus with my heart going crazy, I feel like I might actually be putting enough strain on it to cause me a heart attack which isn't helping my anxieties. My mums away and she's really the only person who can help me when I'm like this but I've called her and she did what she could (which wasn't much from so far away) and now I just feel scared and trapped and I almost want to call an ambulance just to get help off somebody but I know that's ridiculous. Please help , I don't know what to do.
