I know this is a fairly obvious thing about feeling heightened emotions but I had an emotional flashback / memory of something I used to feel and experience all the time when I was younger. I remember how all the other kids would get over something good or bad fairly quickly and I'd be sitting there stewing in it for a few classes or even a few days. 

This could be a negative or positive thing that happened. Say if someone made a funny joke, if it was really hilarious people might laugh up to 10 min max and I'd be there having it play through my head the whole class and try to stop myself from bursting out laughing. I'd even keep covering it with a cough because I didn't want to keep laughing throughout the class.

I'm now 26 and am very depressed and don't feel emotions all too strongly anymore so I rarely experience this much anymore. At least not with the positives. 

I remember how I would want to drag out topics of conversations that would make me feel certain emotions, good or bad, and bring up things other people long forgot to drag out my emotional desires. I used to get pleasure and even enjoy painful feelings when I was younger. Everything felt incredible, even pain back then. To be clear I didn't do anything to hurt anyone or make others feel pain. It was all internal and I was always very quiet about everything. 

This post is quite vague and my memory is shot and I only remember feelings and memories from my past on occasion so I can't think of anything too specific at the moment to clarify more. Do you guys still do this or remember doing this when you were younger? Wanting to drag out certain situations, emotions and people's reactions around you that made you feel a certain way to keep reliving it?
