>>13000337Congratulations, weed turned you into a hypochondriac retard over a condition that is almost entirely genetically restricted to an inbred minority of an ethnic group(hmongs) that only kills 1/50 of the men. Unless you are Hmong or from central southeast asia, your chances of having this condition are about as likely as a sub Saharan African being born with blue eyes.
As you're asking 4chan and not a doctor the only real treatment that can be given out is lifestyle change. The most effective lifestyle change to deal with being a hypochondriac reduces anxiety(which is the root of hypochondriacism) markedly is regular aerobic exercise such as running, cycling or anything that gets your heart rate up. Being aerobically fit will be specifically beneficial to hypochondriac you, as being aerobically fit is absurdly protective against heart attacks, 50 times less chance of one compared to being sedentary (
