I tend to have a hard time setting boundaries for myself too. It doesn't inhibit me on a normal level such as daily functions because Daddy makes sure to remind me to do things. He is the keeper of our relationship and ultimately he takes care of me by making sure I do my chores, maintain my hygiene (which I'm good about by myself,) and take my medications. When it comes to keeping myself in a routine, I helped Daddy come up with it but he, for the most part, developed our system of living. I have a set of rules (as most little do,) as well as have a rewards system, a punishment system, and a points system. If you need help setting boundaries for daily life, there are charts online that may help you with keeping on track! c:
As for telling people no, I also have difficulty with that. What you can do is try to remind yourself that saying no is definitely okay! If it is in your best interest physically, mentally, or emotionally, you ultimately have the right to say no. Please never forget that!
