My Sister’s Coming

My sister is coming to town soon for a visit and we have other family here she’ll probably stay with. We don’t get along and I’m thinking of leaving town while she’s here but then feel like that’s pretty obvious and could be hurtful. She’s not even here yet and I’m stressing about it. I’d rather leave and not deal with the stress but then I feel immature and not in control – like running or hiding to avoid her. Can you help me with some better thoughts or actions regarding this? I’m trying to balance my needs, her feelings, my feelings, being mature, not leaving just to escape, etc. We’re both in our 50s and the distance/discord between us has been in existence for years. How can I be more emotionally adult about this but take care of my own stress level too? Thank you.
