I'm too incompetent to change my life

I'm a 30 year old woman. I hate my life. I work full time at a grocery store to feed myself. I'm really good at my job but I'm already getting trapped by the grind and I don't want to spend my life working. I'm also in a relationship with someone I love but am not compatible with. I know that I don't really have problems compared to other people and I do appreciate what I do have. But I don't feel like I'm living my own life, I'm just surviving other people's expectations of me. I don't really know what I want but I do know what I don't want: I don't want to work in a grocery store or any retail job ever again. I don't want to be in this relationship. I'm scared that I will have to uproot my entire life to make a change, and whenever I think about that I just get overwhelmed with the amount of work that it would take to do what I want and I end up doing nothing at all.<br><br>Edit: Thank you for all of your advice, everyone. I did end up breaking up with J and a few weeks ago I quit my job. I was very happy until the anxiety hit and I realized that I had no way of paying my bills anymore. I took some time to collect myself and get a new job working in a lab, which is more in line with my interests and will hopefully be less stressful. I still have a long way to go before I will be happy with my life.
