I'm thinking the opposite direction of previous posters. I'm not exactly certain how old you are, but I'm guessing under 20?

I think your feelings are normal reactions and the result of a normal need to "grow and leave the nest" so to speak. This is terrifying for a mother who spent years taking care of all your needs and being the most important person in your life. If your mom stayed home with you or you are the youngest child, she may be feeling conflicted.... Both happy to see she has successfully raised you and alternately terrified of the "what ifs" when you ultimately move out on your own.

That said, as an adult child living at home, it's doubly important that you pitch in with housework and also, try to steer the changing dynamic between you to something positive. Perhaps, pick a day of the week where you have a standing lunch date with your mom. If its Wednesday, then every Wednesday, you and mom go to lunch, just the two of you. Even if it's sandwiches in the park. This accomplishes several things: it shows your mom "hey, I'm grown but I still care", gives you positive time together, and will build what is hopefully a lasting, positive ritual.

I know all too well what a toxic mother is like. It doesn't sound like your mom is toxic... It sounds like there are growing pains and perhaps some expectations you each had that you failed to inform each other of. Perhaps it's time for a genuine heart to heart and some gentle but firm boundaries. Good luck.
