you have so much more potential. You have family, friends, etc. who care deeply for you. If you say they don't care, tell that to the 1300* people who follow you. We all care about you and your safety. 死なないでください。

*1321 as of now

だめです。

Please Google translate it because i don't want to make @-Russia- feel worse. No offense to you, it's just that I don't want her to get upset. ”死んでいい？”

it means Good to die

Once again, it is sort of right depending on which context to put it. However, it's incorrect. I don't want false info to spread, so I will tell you this: The "いい" can be used when asking permission to do something. For example, you can say "ねてもいいですか？". This is asking if you can go to sleep.
