Quit playing regular matches for a while and stick to just a few TT per day and read some chess stratety (maybe derive some new chess theories). Also make sure that things are going well in the rest of your life, if they are not they could be affecting your chess game, and much more importantly the rest of the your life. Also, TURN OFF welcome new players, in a slump that is a bad function to have on because you will likely play people who are well over/under 1200 and it gives you a bad idea of your rating.
