Thinking of rehoming my cat

I am thinking of rehoming my cat . I’ve posted about her a before and took suggestions, I bought her a scratching post and she has plenty of toys, I play with her pretty often. She won’t stop scratching me and I have scars all over my body. She will just come up to me and scratch me and it annoys me so much. Idk what else to do. I cut her nails . She won’t use her scratching post. 😒😒 I feel like I can’t handle her considering I have a very busy life. I love her but she has major behavior issues.
