This happens to me pretty frequently. It can be a day, week, or even a month where I have zero desire to try and talk to people. It just doesn't feel worth my time. I don't know it almost feels like its not enough, like its too much loss for not enough gain. I hate feeling this way because I feel bad about missing out with my friends but sometimes Id rather die than talk to anyone. People have been starting to get worried and I think a lot of people think I don't like hanging out with them. I do, I just don't have the mental energy a majority of the time. Its pretty frequent too, and happens at least once a week. 

How am I suppose to get better if I keep isolating myself? Trying to push myself to hang out with people, but half the time I just want to go home and lay in bed. However, I will go to the end of the world to talk to my FP, and that's the only person I want to talk to a majority of the time.
