I have a great friend who I've known for 6 years. In the last two years, she has been asking me to take her son to college a few days a week. It started off as a 1 time thing, but now its become all the time. I find it quite sttressful, cos the son is never ready on time, and it makes me run late for everything ive got to do. I've been sick in the past, and she still expected me to do the run. She did it today and was ranting about how she was running late and how he wasn't ready. I want to tell her that I cant do it anymore, coz my mental health isnt great and im feeling too much pressure from her, but i know she'll take it personally and get upset. she asked me a few months ago if she was taking the piss, and i wish id said yes, but i didnt want to hurt anyones feelings.
I feel really stuck in a rutt about it. I know she'll take it badly, but I cant help feel taken advantage of. I dont get petrol money, and yes, im goin in that direction, but i feel like i have to plan my week around her son, which is rubbish. Any advice on how to broach without resulting in afallout?
