Lost in depression and suffering from a lost sense of self.

Hi, I am new to this thread and the 7 cups community in general. I have been struggling with depression in some form or another since my teenage years. I am no longer a young man and am firmly middle aged. For the past four years, I have been back in school and working towards my K-6 teaching degree, working as a parapro in a resource room, and taking care of my family. I love my job, my kids, and my wife. I feel I have a strong support group and a good life, but I am often very despressed. It drives me crazy because I know I shouldn't. One of the biggest issues I have now is the load from school. I am nearing the end of my degree path and I am exhausted. I have spent the last four years working full-time and going to school full-time, while doing my best to balance my life at home. During this time, I have completely forgotten who I am. I rarely have time to do anything other than school and when I do I either can't figure out what to do or what I choose is incredibly unsatisfying. I know this is playing heavily into my depression but I don't know what to do about it. I can't stop going to school. I only have a year left and being a teacher is my dream. I also can't stop working. I love my job, the school I work at, and the teachers/kids I work with. My wife says that I am just borrowing trouble and maybe I am. I am hoping that by having an opporunity to talk about things and hear other peoples ideas, success stories, and failures it may help me find my path towards feeling well again. I found success in overcoming severe anxiety after fighting it for almost 15 years and I hope to overcome my despression as well.
