Relationship with sister – trying to be proactive about visit

I am going to visit my sister next week with my children. We have a complicated relationship and it went very badly the last time I saw her. In the past I have overeatten and overdrank to deal with the discomfort.

Since I want to avoid theses behaviors, I thought it would be a good idea to be proactive with some thought work so I can better manage my mind and my behavior around her. Unfortunately I feel a little lost on where to get started.

A lot of her behaviors drive me crazy like she talks incessantly about herself, she’s very high maintenance but has no idea that she is, she’s very critical of my son but not my daughter. I realize logically that these are all thoughts, but I am having a difficult time realizing that in practice. Any suggestions on what I can do over the next week would be great!
