I understand what you are talking about, I have been through this many times, although I did not lose so much, but my moral and psychological state was about the same as yours. In such situations, I always stopped playing for 2-3 months, maybe even longer, but then all the negative emotions go away, I forget everything bad and start playing again. I once talked to experts at one of the poker schools, described my situation to them, told them that I have been playing poker for 16 years, and it would seem that I know everything there is to know about poker, and nevertheless I constantly get into such situations. One of the coaches listened to me, assessed my gaming experience, and said: "What is happening to you is variance. You need to learn to overcome it, and everything will be fine." I think he is right, and the main thing in such moments is not to start tilting and learn not to lose a lot, and in those moments when negative dispersion ends and positive begins, you need to learn to win to the maximum and then there should not be such problems as you and I have.
