I'm Starting To Really Hate Playing Rocket - And Not Because He's Bad

It's because people hate Rocket.

Nobody is ever satisfied with what I do, even if I get MVP. Doesn't matter. Not a single person has ever appreciated what I do in this game as Rocket, not even once.
I've seen a lot of "man hulk you're the goat" or "luna i love you" or "best loki ever istg" or "jeff ur awesome", but nobody has ever given any appreciation to me, not a single time, and I don't think I've ever seen it given to other Rockets on my teams either.

Instead, I get flamed a lot. People get pissed at me all the time no matter how well I'm playing or what I'm doing.

If I heal a ton, like 41k healing, then I'm a "stupid healbot" and "you're a support, where is your damage?"

If I do healing but also do a bunch of damage and shred through tanks and go after iron man, then "where tf are my heals?" and "no heals gg" and "stop playing like a dps you ####ing re####".

Nothing I do is ever acceptable to people in this game. I can't win. People are usually mad at me no matter what.

I was blamed solely for the loss this match because I was a "stupid healbot". A lot of my team got mad at me at the end.

There really didn't seem like... well any times that I could go in and shred a tank. I'm 100% sure if I attempted to do that I would have blown up instantly. I did kill some people though.

Why does Rocket get so much hate and no appreciation? In Overwatch there's also a healbot character similar to him, Mercy, but everyone is always super grateful to Mercy. She always gets commendations/upvotes and it's very common for people to type "ilu mercy <3" at the end of a match.

But Rocket gets none of that. Instead people hate his guts. Why?

Edit: Thank you for all the kind comments. I can't respond to all of them but I'm doing my best to read them all and they're very appreciated, thank you.
