Sort of my story but more about advice

I was just wondering how others moved on from missing something that was probably not a good thing to begin with. I am not doing anything or acting out. I am just trying to make sense of my emotions. Also, what makes it more difficult is that I don't really have anyone to talk about it to. Its not something that the normal person goes through.

The way I explained it to myself is that I dont miss the R- or the bad stuff, but just the company. Because my mom has many boyfriends. So I never really was the centre of attention.
