Prayer Requests - Healing from negativity

Please help me pray to remove any negativity from me, my soul and my marriage. I am becoming so negative that I am avoiding my husband’s family as I find them toxic to me. And it creates anger and resentment not only to me but also to my husband. We haven’t talked in days and I don’t know if he still cares or loves me. I don’t know where this resentment to his family is coming from. I don’t want to be with them. I hate spending time with them but I can’t avoid it. Sometimes I pray that they die so that I don’t have to see them anymore. I know it’s wrong but I can’t help it sometimes especially when the holidays are coming. Please pray for me. Thank you!
