You're right, there are a lot out there like that, maybe more so now with all that's going on. I think some people just don't like seeing others happy when their lives aren't. They may not understand what they are doing, but many do. Some could be jealous of how you are or even that they aren't being mean on purpose, but could be thinking they are helping you so as not to get hurt by all the others out there. For whatever reason, your brightness has attracted some of the darker elements.
But know this, your "rant" though necessary to help you isn't a bad thing. We all need to let out the steam of pain or sadness or disappointment. You are sharing something with others and that's always a good thing.
I'm an old fart compared to some and still relatively young compared to others, I've seen a lot in my short life and not even close to everything, but I still try to find the lighter things in life and people, I still try to do what is the right thing no matter what, because if you can pass that brightness to just one person, that's a lot. They might have needed that to help them through their darkest period. I have my own darkness's to fight and it's been people with that light inside them reaching out that has helped me so many times. I value them so much. I didn't ask, but they offered.
I don't know if anything I've said makes sense or is helpful but don't give up is what my motto is, then again, I'm a stubborn cuss and so far, hasn't figured out how to give up.
If you're being taken advantage of, might be a good time to pull back some, even go so far as to say something. Some might not realize while others will be offended and those are the ones to distance yourself from, even if for only a little time. Whatever works for you.
You're not an idiot and this world is full of all kinds. There are still decent people out there. I've found a couple here and elsewhere. I hope you feel better, I hope your rant helps and I hope that maybe something I said just might make some sense.
Be safe and take care. 🌷🔆
