I agree with the others above, it does sound like you could be in a depression of sorts. The bad thing about being depressed, is that it is real easy to get there and stay there because it just feels like there is no reason to not be there. I've been there several times myself, and one of the main components of it for me was isolation - I just didn't want to be around anyone or talk to anyone. Try to keep the communication open with your family, friends, and even here, too, so that you are continuing to talk and connect. Let us know how things are going.
