I am literally seething with hatred constantly

I love my children and some of my close family members like my parents. But a person can only take so much. I’ve been in 3 abusive relationships and I was stuck financially in two of them to the point where instead of feeling sorry for myself and hating myself I started to develop outward hatred. Now I’m just jaded and hate everything and almost everyone. Even though I am out of the relationships, I have two kids with two different people who didn’t know their abusive side until I got pregnant. They are still abusive and call me names sometimes when we exchange the children or are just mean and with every ounce of abuse just makes me seethe with more hate. I know I consume too much social media sometimes which makes it worse but I’m already just a hater anyways. I hate the way people drive, I hate my coworkers, I hate the greedy rich people in this world. Also this came with becoming an adult I guess because I wasn’t like this as a teenager. I always wanted to help people and make their lives easier. Now part of me wants to make certain peoples lives worse.
