Is there a way to get better for sure?

I've been thinking is there a way to get better and turn your life around or is it just trauma that keep changing shape and coming back to me as different problems. Is there ever going to be a point where I'm happy and not seeing the effects of my past catching up to me? Is there ever going to be a day where I don't react like a victim and ruin things? Am I ever going to get better or am I just going to keep living the past in my head. Am I always going to look at people with complete distrust or am I going to be able to fall in love and have a good life like I've always wanted?
