My parents are also very much like this in the sense they will do everything for me which i don’t necessarily think its a bad thing. I could very well be wrong but maybe you could be taking this the wrong way, they may do this for you just out of protection even if you say you are fine they still see you as their little child (not in a derogatory way) I don’t think the issue is patience they have had you their whole life this should be regular to them. My parents say they don’t even notice it because iv had a stutter for as long as they remember anyway.
