I have started a new job, there are a few people that I get on really well with and want to be in their company and talk to them all the time. They listen to me, joke with me and I think, genuinely like me. When I am not there or when one of them is off for the day, it makes me feel a bit lonely and I actually "miss" them. I have the same sort of feelings towards my counsellor, when I leave him I feel like there is a pit in my stomach.
what are these feelings?
