Ok so first of all, keeping what around here we call “good spiritual hygiene”, meaning, a combination of keeping ourself an your spaces clean of negative energy and unwanted beings is a basic part of learning how to be a functional mage and avoid astral parasites and freeloading time wasters:
If you already have an attachment that’s not wanted, which sound like the case, then the first thing ou do is communicate and tell them they must stop and leave. After t hat they’ve had their warning and you have many ways to make them leave. You are stronger and there’s no contest really.
Always remember that like attracts like. Given your username, I’ll run with the example of a lot of lustful energy attracting astral entities that feed on that, and will try to make you feel even more to get more food.
The Gnostics called it feeding on “loosh” it’s a very old idea but everyone’s problem. Hence it being a mage 101 type activity to protect yourself from such things.
