What to do about my mom?

Chris....I think you should let her know that right now you are good with granddaddy, and you are not ready to leave. I was in the same situation and I really understand where you comin from. Ask mom if she would like to visit you and granddaddy.....you and mommy needs to develop a mother and son relationship first, so that you would be able to deal with her as well as she can deal with you! Try that son and see if she will be willing to do that!!
