I have a friend who is constantly texting me and phoning me up to ten times a day and wanting me to meet up or do things for her. She suffers with depression and anxiety and doesn't work so she has more time than me ( I work full time). She sends long rambling messages which often make no sense and asks me to do things for her (take her shopping, go to the doctor with her etc). I want to be supportive but it's becoming overwhelming. I've tried to set some boundaries (such as saying it's difficult for me to reply to your messages when I'm at work) but it doesn't seem to help. I don't mean this to sound unkind but she seems incapable of functioning as an adult (she's in her 40s) and I don't know what to do. I'm happy to do things like go to the doctor with her if she needs support and I'm happy to take her shopping as she's too anxious to drive, but I can't do everything. Every time I speak to her she just talks about herself. I don't want to abandon her but I don't know what to do for the best. I've been really ill myself recently (currently recovering from cancer) and whilst I want to do what I can to help her, it's just becoming too much. I know she's suffering and needs support but I feel totally overwhelmed. To be fair, I don't think she's deliberately using me. I think she's just so wrapped up in her own life that she can't see beyond it.
I want to be there for her without it taking over my life, but don't know how to.
