Ok I think I may have been slightly too harsh was I?

So I recently got into a big argument with someone on the fact that I hate myself and im depressed. He basically kept telling me just to "stop" it and to stop being a selfish brat . Then I basically wrote him back explaining my condition (with a few swears here and there mind 당신 I was kinda over reacting but at the present time I wasn't thinking very much) He then wrote back (all in caps) basically saying how he was supporting me 의해 saying that stuff and that I should "fucking " smarten up then this part I think I went a bit over board I told him basically to fuck himself and layoff cause I been like this for years and I explained in 더 많이 detail about my situation only this time all in caps while telling him to fuck off and saying he was 연기 immature 의해 immature I called him a little kid meanwhile I know hes old enough to be my dad . He then messaged me saying how dare I tell him how to feel and called me a 암캐, 암 캐 about 8 times and even threatened me if I ever messaged him again saying he will 신고 me 또는 he will talk to youtube? something like that his grammar is terrible . He also called me a whiner (not sure I spelt this right and spell check didn't correct me so XD)
