My family and neighbors say I can't sing and make snarky comments. I never had singing lessons. Please give advice on pitch, tone, if it's really so bad, etc.

I've been practicing by myself for 5 years, recording myself too all that time. I never sang publicly, my neighbors just can hear me singing because I live in a block of flats. Yeah, I know, every amateur singer's nightmare. Don't worry, I don't want to become a famous singer, I just wanted to be able to sing my fav songs. I'm not gonna get a vocal coach, even if my singing is bad or mediocre, I'm probably gonna quit. But be honest, I will not be mad or sad, by now I just don't wanna waste my time, I have other hobbies.
