God, I need your help..

I dont know what is going on with me, I have been having these things going on with me for the past year and a half..I get weak easily, I cant do any kind of exercise because Ill get lightheaded and out of breath and my heart would palpitate,pvcs. I have to go in for another sleep study today, this time with the mask, because in the past week, I would keep waking up around 3am lightheaded with double vision and palpitations, then I would try to go back to sleep again, wake up dizzy and lightheaded again, (feels like as if I had no air), and have double vision bad..

When I talk for a certain period of time, I get more lightheaded and my lungs feel as if they get tired and that's when that "elevator vertigo kicked in worse..
I cant leave the house. Im struggling with my eating...My hair is balding in patches.
I was in and out of the emergency room 2 times right along with my Grandaddy (pray for his strength and wellness) he had a high blood pressure.

Please someone, ask God to please will to make me well,mentally and physically... (Im scared) Sometimes I ask myself about my future..I would always have this nagging in my mind saying "look at you, you arent going to make it, its over"..

Please God hear me, someone hear me. I need help.I feel like Im sinking..

Im about to go in for an MRI...and they are using a contrast stuff that I dont know about...Please ask God to help me...

Today, I need help with my nerves, I have certain people in my family that are negative..verbally,mentally,and sometimes physically and they see that Im already struggling with my health..Please God help me..and ask God and Jesus to numb me to these kind of things..I need help..

:(In the past year and a half, I have been having cardiac arrythmias,pvcs,svts(superventricular tachycardia),constant "elevator vertigo" that makes me feel like my head and body is sinking to the floor and it makes me feel as though I cant move and like someone is pumping "helium" into my head.every single day constant vertigo all day..I have been having problems with my sleep. Went to 4 doctors, those four couldnt figure out what was going on with me..I was going in and out of emergency rooms...even on my own bday.. I used to get on the bus and go everywhere or go to school, now I have to have someone to be with me or take a cab to go around the corner..I need someone to plead to Jesus to please restore my mind and body...spirit and soul...and life..I need your help Jesus..please give me another chance at experiencing life..I dont want to just sit next to my window, watching the world you created to just go by...please Jesus bless my health..Someone please pray with me and for me..

And also pray for my Auntie that has been going through emotional/physical things on trying to keep her life in balance..Ask God to help her, give her strength and favor too...I apologize for this long winded compuletter..God bless you for being patient with me too..
