i've been reading up here on seddit for a while now but i've hit a major bump, i can't keep a conversation running.

i've always been a loner and didn't do anything interesting ( playing videogames such as WOW ) so i can't really contribute to many topics so a short while after a conversation starts my mind just goes blank. i don't know what to say, don't know any funny comments ectect. it's mostly the usual talk like school, hobbies ectect. i know those could be great topics to keep a conversation going but i just can't pull it off.

anyone got any advice?

edit: a bit background info. i've had a relationship of 5.5 years which ended about a month ago. since then i've been working on turning my life around, starting with my bad habits like videogames, way to much TV, porn (for those who think nofap i bullshit, think about winning a few hours a day by dropping it), cutting back on my internet usage and smoking (mainly to get more rested). i was also a stereotype "mr nice guy" (still am but working on it!).

in the past most of my contact with people was vitual, read msn, but even on virtual conversations my resources run dry very fast. this hasn't always been like this, i used to able to chat for hours at a time. i know chat isn't the best way for seduction, but at this point i'm not trying to get a girl, i'm trying to become more social.
