Wondering how to work through limiting beliefs about money

I have been working on manifesting for a while and I have seen some success but I have always struggled financially. I feel this is because I grew up in a home with parents and family that always focused on lack and never on abundance. Constantly saying "I'm broke" and reinforcing that lack. My parents were always worried about money and they often shared these worries with me and my siblings. I have begun to work on changing how I talk about money and this has helped immensely. I have also begun to focus on abundance and thankfulness for what I have. I am a very lucky person and have lots of wonderful things in my life to be thankful for so this isn't too hard. Another big reason I am struggling, I believe, is because I have a lot of negative associations with money and success. I run a business and I would love for it to grow faster and become very successful. I often think about becoming a millionaire and whenever I do I find myself immediately justifying why I deserve it by bargaining and thinking things like "if I am wealthy I will help people, start charities, give to family" etc. and I think that I tend to view rich people or wealth as being "bad" or negative. I have noticed myself feeling guilty for wanting wealth when so many people are struggling, dying, have nothing. I am struggling with how to move forward from this belief. Any suggestions? Does anyone else struggle this way?
