I don't know if this is the right place to post this, but I think probably only those with experience of MH issues in the family and friendships will really be able to appreciate the situation.
Three years ago I got talking to Lou at an event I was attending for work. We hit it off. She had recently moved to my city and so we arranged to meet for coffee. We're interested in similar things, we share the same sense of humour and we started to become good friends.
Our lives are very different. I have a long-term partner: Lou was recently divorced after a long marriage. I have no children and she has three young-adult children, two of whom live at home with her. Her 17-yo daughter hasn't attended school for several years, self-harms and is receiving psychiatric support pending diagnosis. Lou tends to bring her with her wherever she goes and so her DD often comes to our meet-ups. Unfortunately DD is so fragile that her needs have dominated a lot of our plans. Things get cancelled or changed at the last minute or DD gets triggered by something and we have to leave the cinema or the cafe or the place we're in. On top of this her son was diagnosed as having Borderline Personality Disorder last year and has given up university and returned to live at home. Inevitably a lot of our conversation and contact has revolved around her children and the various crises they go through. I've been as understanding as I can. Her DS has made several suicide attempts and on each occasion Lou's called me and asked for help to get him to hospital in the early hours of the morning or to sit with her DD while she takes him in. Our friendship is now dominated by her children.
A few weeks ago she was very stressed about something and sent me a long, complex What's App message which I didn't spot for a couple of hours. When I read it I got the wrong end of the stick and so my response wasn't what she'd expected. She messaged back telling me how unhelpful I'd been, then told me that she needed space and blocked me on What's App.
I sent a text explaining my misreading of the message and saying that I could understand that she was stressed and needed some space, hoped things were okay with the children and left it at that. I heard nothing for around six weeks and frankly began to feel quite relieved to be free of all the distress.
Today I was away at a festival when I got a message from her asking me to come to her house urgently. Her son had smashed a window and hurt himself and she needed to get him to hospital for treatment. I called her, explained I wasn't in the area and we had a brief chat about who else she could ask for help.
I've now had another message asking me to meet her and her daughter for coffee and cake on Monday. It's friendly, as if she didn't go silent on me for weeks. She seems to assume that everything's okay and that things can go back to how they were. I don't want to do that.
Has anyone else experienced anything like this? How can you be supportive to a family in this very difficult position without ending up feeling that their needs dominate everything? Is it possible to have a real friendship in these circumstances?
