22years old methamphetamines has flogged me but i dont no what it is

Im 22 i smoke ice, as soon as i smoke my heart races intense and i eventualy cant breath. My chest weighs a ton, i sweet massivily when im not hot. My feet turn freezing. My tounge swells up and tastes disgusting, no amount of brushing or mouth wash fixs it. And ulcers at the back of my tounge. My posture goes funny and i sit and stand in awkward positions, my speech goes funny and my voice constantly changes. Sometimes i feel like im urinating my self, my nose and sinus also turn completely blocked so i dont no how bad the smell gets but from the indication of my mates its pretty bad. Not to mention how bad the taste in my mouth is. Ive tryd breathing techniques but they make it worse cause i feel like i breath trapped air into my stomach. I also cant fart or poo when im on drugs. And relaxing is rather dificult. I no i should stop. But its not that easy. Ive been on a very large amount of drugs since i was 15 and ive previously been addicted to weed speed ghb and pills. I was able to kick the habits and now getting better with the ice. But need to fix this problems because they are starting to happen sober. Please help. Im not sure if its multible problems or something simple. Ive never been aware of how my body acting until the last few months
