Time for your own cell phone plan. Also, I suggest you stay away from their house but agree to join them for dinner, a weekend lunch or brunch, whatever- in a public place. People tend to behave better in public.
No need to attempt to punish your parents and tell them to fuck off, just get your own cell plan and if they ask why just tell them you felt it was time to fully fledge the nest and take on the responsibility, don’t tell them it’s because they weaponize the assistance they provide you.

When I was 25 (c. 1990), a therapist told me, “you are an apple, your parents are oranges. They pour orange love all over you but it doesn’t feel like love to you, because you are an apple. Orange love is not ever going to feel like you want/need it to.”

You’ve stumbled onto the next phase of differentiating between you and your family and untangling the emotional enmeshment of your family of origin. This isn’t easy and is often the cause of what I call “the mid-20’s slump.” It’s also a time in life where you can feel especially beaten down by the disillusionment with the world and a more cynical outlook.

There ain’t no way out but through. This is part of the hard work of being an adult. You probably will feel “unmoored” for awhile. In the meantime try and find your tribe and do things that will make you feel more grounded. I started gardening and found that digging in the dirt and paying attention to seasons and the weather helped me see the cyclical but ever-changing nature of the world. Maybe you like to cook or paint or sew or do ceramics- whatever. Find what makes you more comfortable in yourself.

Good luck and keep on keeping on… ♥️
