Why do my wall outlets make things shock me?

So I’ve lived in this house for a few years and what I’ve noticed is that if I have something plugged in, a t.v. for example, when I touch something metal on the tv it shocks me. Or when I plug things into my computer (that’s plugged into the wall) those things shock me. It makes it very difficult to do much of anything when I can’t touch things like my phone when it’s charging for fear that it’ll light me up. This only happens in one side of my house (mine and my sister’s room) it’s a constant electrification as well, not a one time shock.
