How is your quarantine? Mine sucks

Never across my mind to complain about this quarantine life due to covid-19 pandemic cause I'm sort of enjoying this kind of *doing nothing* life. dont get me wrong, I'm not saying that I'm enjoying this pandemic, I'm just gladly doing what we've been told...to stay at home. But apparently some people really do (complain) a lot. And they are commenting on mine. My own life. My doings. Like WHY CANT U UNDERSTAND  THAT IM JUST HAPPY BEING ALONE. CANT U SEE HOW HAPPY I AM? (screams in cody)
I've been receiving negative comments during this quarantine just because i never step a feet out of my room unless it is really necessary.
Yes, from my own family (not my parents, cause they are nice).  
They were commenting about my bad skin, how much i lack of vit D and UV, (they say like they know it so much uhh), and how skinny i am. when in reality, i appear like this everyday man,  this is the most normal and usual i look, what do they expect actually? I've been this skinny since i was 6, even since the days were still normal as i spent most of my time outside. I barely gain weight cause this is how i am ever since.
As someone said that our body is something that we should never apologize for, I try so hard to keep that in mind too okay.
They be saying that throwing negative comments is a form of their concerns, but this doesnt feel right to me. I could never swallow it just like that, so i snap back, and i fight back. Never say this kind of stuff again, at least not in front of my face cause it hurts me a lot you dont even know.

P.s : this is just a temporary rage.  i will be fine and act as if nothing happened in the next day. Dont worry! I forgive.
