It sounds like you have a lot of stuff going on in your life that is causing so much stress and depression. Usually clinical depression manifests for 2 months or more and isn't necessarily based on circumstances, but I'm not saying you don't have it, however I would suggest maybe seeing a counselor first? They would better be able to tell you if you need to try some medication, or just start with counseling to deal with life issues. Wish you the best.
