You could be around too many depressing situations. Group homes, helping people get their lives going again, your depressed friends. You could be taking in the feelings of these people a little if you are an empath. I don’t know much about psychology, but I do know this same thing happened to me when I was volunteering and only around situations where there was little progress and little hope. I started taking on the emotions of those around me. If this is the case, you can spend more time doing the things you like (or used to like) a little bit each day. Spend time with a few very positive people to help you balance your friends who are having a hard time. Force yourself to do the positive things and work toward a goal for yourself (one that you choose…not a goal that you think you “should” do or somebody wants you to do). What have you always wanted to do? Take a tiny step towards that thing each day. You have to find something that makes you want to get out of bed in the morning. It will be slow, but have patience. It will get better if you take these steps.
