I Still Live With My Parents

I still live with my parents and sometimes I feel ashamed. It has it positives and negatives. In the long run I'm saving money and I'm being taken care of (I don't have to buy groceries, pay the bills, etc., but I also feel lonely at times. I don't want to hang out with my parents. Usually I'm okay with hanging around by myself, but at times I feel lonely. Like how much better would it be if I had a friend or a buddy here to keep me company. It's bitter sweet. I could move out if I wanted to, I've got the funds to do so, but something is holding me back that I can't pinpoint. I don't know if I'm just comfortable here and being out on my own is a little freightening, or what. Does anyone else ever feel this way? Stuck and lost about what to do?
