Help me fix me chess psychology!!

Recently, my rating went down a lot of points(-150) and because of that I got really frustrated and demotivated at chess and life.

My behaviour offline was very rude and angry while I really controlled my behaviour while playing online. But yesterday, I couldn't do it anymore and smashed my computer which I was playing in. The screen broke eventually leading me to replace it with a new one. I used to use that computer for 2 years. My family was shocked by my behaviour and insisted I go to the medic. The medic told me that I have temper issues due to recent happenings and told me to take some rest. I didn't do it. I was really addicted to chess.com. And, you guessed it, I lost a lot of game again which led me to vent my anger on my family. I really hurt their feelings. I acted tough and I didn't owe them an apology. That was because I tilted 100 points. I tilted more today and I starting to think that I should quit chess forever. Part of me says I shouldn't and part of me says I should.  I'm now taking stress tablets. For any chess masters out there, please give me some advice! It would be really helpful for me!!
