Hello I donated blood twice 3 years ago and sense I feel weak at times I don't feel right mentally the only way I feel better is if I drink vitamins eat healthy but when my period comes once every year I started to feel the same and I recently tried Crystal meth 10 months ago can it have caused my anemia to be worst or it's anxiety? Cause before the meth i would get infections all the time after sex I. Would have trouble sleeping lower and upper back pains and really bad chest pains and feeling of burning inside also and again my mind didn't feel right even before I tried the Crystal meth please help! !
