The long and hard road

I moved to a new city 4 years ago. I made sacrifices and took care of my brother for 2 years. I worked up to a retirement home with decent pay and began serving when some harrassment began. I was frugal, I biked to work, my every thought was saving for a future I could have. I reported a cook for disposing over 40lbs of compost into a trash every night, and I set some standards. The place was like a cult, and I had my bag raided, called names, harassed, and at the end of it all, my phone destroyed right out of my locker. My brother could no longer take care of himself and needed extra support. I made sure he had it. He got the room while I had a curtain bedroom beside a kitchen. When he moved to an assisted living home, covid began. I had the eye for a server and told her I didn't want to feel alone anymore. My anxiety stopped me from opening up in person but we talked for a year. I learned that a cook I was working with was a sexual predator, the company was defending him, and covering their tracks. The cooks ended up trying to ruin my reputation after the predator was fired. I lost my job without cause. Someone made fake Facebook accounts exclusively to harass me after.. I told myself no one would feel sorry for me, I worked hard and when my hours were cut, I got into investing. I made 40k at the top and lost it all recently. Market crashed, poor gambling decisions to make it back, no emotional support. Where do I go from here? Does one just start up in a new city, put their head down until they're 40 and become Adam Sandler's character in 40 year old virgin?
