I have people pleasing tendancies which stem from my childhood. Most of the time this doesn't cause me a problem as I'm aware of it and can pull back when I notice it happening. But, I have a 'friend', who has had quite a tough few years with health and relationship issues, and to be honest i feel quite sorry for her and so try to be nice. But I've noticed over the past year or so that the friendship has become unbalanced and its always me helping out her and never vice versa. I've started to say no to her occasionally when she asks for favours, but when I do, I often end up feeling bad and relenting.
For example, yesterday she sent me a message asking me to Skype so she could chat about something related to her work that I'm an expert in. I was feeling a bit ropey (not Covid related) and couldn't face skype so asked her to email me the questions, which she didn't. Today, I have this guilty feeling hanging over me that I should have just given her a bit of my time, and that now she is probably pissed off with me.
How do I get over these feelings? I guess some counselling is the answer but in the short term, how can i say no to someone and then just let it go and not feel guilty?
