I’ve been in diapers for some time now. My caregiver bought some special adult Pampers. Should I let her put them on me?

Yes, why not? You should allow her to put them on you because she’s there to care, support, and love you. And she’s showing you that with the bladder issue you’re going through, she’s there by your side, and you’ll both get through it together. And in addition to the unique adult diapers she got, you must be more comfortable and secure than the ones you are wearing and absorb a lot more liquid.
But remember, once you get used to these diapers, they become permanent in your life, so try to consult your doctor and seek ways to avoid using them.
