How can I recover my health after smoking meth?

Ok. Well I smoked weed since I was 15. Until i was 17 my high was the same everytime.(Yes weed is bad and blah blah blah) after a while i started to experiment with other drugs. such as e pills prescription pills coke(smoked it) and some alchohol. after all that, i still felt fine. I smoked weed, and it still felt the same. But then i got into meth and everything just went downhill from there. i only smoked for about two to three months before quiting out of shear will. i just wanted to know if its possible to get your health back after smoking meth. i feel like my breathing has shorten/gotten heavier. i got sucked in and im really skinny now. i feel like sharp pains in my midsection like if i was getting poked with a needle or something. and i cant eat like i used too..i only eat atleast once every two days. or one. weed doesnt feel the same. i take one little hit and i guess im tripping out. i used tp be able to smoke atleast a dub without getting high. please, if anyone has anything to slowly get my health back, as in like something for my lungs mostly, that would be nice lol thumbs down if your answer is ****** gayy :p
