You didn't cause their illness and you do not control it either.
Hi Letloverule and mssalty, thanks for these posts. I really appreciate this last sentence. I think I am going to repeat it to myself quite a lot today! I am wondering lately about the impact of my partner's illness on myself as well. It has taken a huge toll and I am still coming to terms with it and really... .sigh... .just looking for ways to keep myself happy and whole with all this going on around me.
My advice overall, if I am in any position to offer any, is to try to slow yourself down so you can go back to being yourself and having a clearer sense of what other's behavior really is instead of thinking everyone is mad at you or "ascribing bad motives to them". The slower we let things be the more time we have to think clearly and see more clearly. Meditation, even a small amount, helps with this because we train ourselves to see our thoughts (and therefore can be less attached to them) and to recognize the pain of others (and therefore can have more compassion). The good news is that I am sure you will be able to get back to a good place with yourself on this topic though! Just take it easy and forgive yourself and let yourself be you again.
Time will make it better.
