sister question

I don't know if I can be of any help at all here but have you considered telling her kind of what you have told us, like maybe telling her that you love her and enjoy spending time with her every week but your schedule is so busy and you need quality time with your family, so maybe just on one day you 2 could go do something together? Would that work? I am not sure how often you see her now but I would imagine there's gotta be some way you could let her know gently that its too much and needs to be a little less. Once I had a friend who I spent all day everyday with and we started to get on each others nerves so finally I just told her, I enjoyed hanging out more when it's not everyday or every other day, just once in awhile. It worked and we're still friends, of course it could be different since you 2 are older and sisters, but I'm thinking it would be better to talk it out with her honestly than just avoiding her or suffering without saying anything and hurting yourself and your family, ya know? Good luck, Rhiannon
