Why do people/ does this person want to ‘help’ when they find out im depressed (lol but never before)

I live with my parents unemployed, haven’t had the motivation to do anything for a while but still want to be an artist (also my mother’s an artist) and one of her customers who’s become her friend online even though she lives in america and we live in the UK (also she’s Christian, I’m atheist) wants to send me money to ‘help me start my own bussiness’ . I don’t know her, I’ve never talked to her, but according to my mother since she has no children and she’s been talking about me, she feels close to me. This makes absolutely no sense to me, I’ve been trying to tell her to stop but she’s adamant about sending it. Do you think she wants me to talk to her or do work for her? Or do you think she’s doing it because she ‘believes’ it’s right? Or does she think I need more help? I just want to be left alone to make my own choices but everyone tries to force their damn kindness on me, it’s like an extra pressure cause i know I suck and I’m not grateful enough, hell I’m to lazy to take everyone’s ‘motivating’ words and actions to do anything. Why can’t they just hate me and be honest? Or at least let me go
