Based on what I’m reading so far you want to be polite and be a good friend. But you also seem emotionally triggered when seeing a message from her. So I would say something along the lines as ‘thanks for supporting me still. You’re a good friend. I’m still in need of space tho. So please, give me the space I need to find myself. I promise to get in touch once this is all over.’ Something like that. That to me is understanding, seems polite and should get her off your back.
