As BXNNXD says: meditation might help.
It`s for everyone who wants go try out something new. With time it`ll improve your physical and emotional condition. In short, you won`t give a sh*t about alot of things that really doesn`t matter.
It does "cure" alot of other problems not only your stated one.
Can approve myself. Tried out, helps a ton.
You might be skeptical bout this, but it`s not hard at all and you have basically nothing to lose.
Hope, you`ll get better.
