What is wrong with me?

I woke up Wednesday morning at 3. Well more of was jolted out of my sleep. And everytime I tried to go back to sleep I would get this anxious feeling and I'd immediately wake back up. I also have some numbness in my left eing and pinky finget and I have some pain in the respective shoulder blade. Sometimes I have an anxious feeling and I can't be alone for too long or I start thinking I an having a heart attack. Idk what's wrong with me.
