My mom spends so much time obsseseing over what i need that she refuses to except that she needs to get things done for herself like she needs glasses and she needs her dentures redone, i pretty much have to tell her i am not getting anything done till she does witch makes me feel like crap becouse it makes me feel like i am bulling her
Instead of disagreeing and prolonging the lack of consensus, I would agree with her and tell her you're taking steps to address the issues over which she's concerned. Give her dates when you're seeing doctors, etc. Tell her you're concerned about yourself as well, and want to make sure that her worries are addressed, BUT that you also need to ensure she can accomplish whatever needs to be done for her.
If you refuse to "get anything done till she does", not only will you feel bad but so will she as you're invalidating her perhaps legitimate concerns for your welfare. Recognize their legitimacy and act on them. If you don't take care of yourself, you're going to fall prety to caregiver stress a lot sooner.
Let her still be the mother she is, take her advice, and make plans for both of you to accomplish what's needed.
Then treat her to lunch or dinner afterward.
Do you handle her finances, and if so, can you determine whether there is sufficient money for both of you to get new glasses?
You say she's supporting you because she doesn't want you to work...what do YOU want? Not wanting someone to work gives another level of control as unless you're gettin SS you're completely dependent on her.
Sounds like a part-time job might help break the financial dependency that seems to be a back-up excuse for not getting the treatment she needs. And do try to help her with the finances so you can determine if her financial concers are legitimate or just excuses.
