Mediumship Woes and something's not right

We are in the subreddit of Medium with a concerning post about feeling negatively impacted by the stresses of mediumship. Let's see what's happening here and where the power lies:

I don't want to be a medium anymore

It's terrifying. It makes me feel crazy. I feel overwhelmed constantly, scared, frantic, I don't know when it's going to happen to me again like I hate it. I hate it.

Had such a bad experience yesterday. I don't know when I'm going to be able to deal with this kind of stuff, ever. I'm sorry that dead people are so confused and lost. That sucks. Idk what I am supposed to do. I really just want them to leave me alone.

I guess I wanted to ask.. Is it going to affect me long term if I don't allow them to contact me? Is it... Okay to ignore them? I want to be present in this life. I'm so tired of spirits and random shit always bothering me. I really just want to be left alone. No spirit guides, no dead people. Just leave me alone.
