Dsis was diagnosed as bi-polar (apologies if that is not the correct terminology) several years ago and has been hospitalized many times since. There is a quite a large age gap between us and we have never been particularly close but we have always got on fairly well.
About 3 weeks ago she was hospitalized after another manic episode. Last week she sent me a particularly unpleasant text message. Amongst other things she said she has hated me since I was young, called me a pathetic, evil parent and said that she would be calling social services on me immediately as she heard I was taking the DC to visit our parents soon. She is accusing our dad of sexually abusing our two brothers (neither of them have ever said this happened). It was truly hate-filled.
What I found particularly unforgivable were the comments she made about my DC, using vile racist language to describe them (I am Black and DP is white). I can’t move past this. I know she is mentally unwell but something about the message tells me that what she is writing is what she has truly feels. Some of the comments were so specific and clearly articulated, I really don’t think it is entirely the illness talking. I actually find it unnerving that she has stored up this level of hatred against me over all these years. My brother has said I have to just let it all go as she is unwell and she has insulted him during her episodes as well.
I can't shrug it off. I have blocked her number. AIBU to just leave it blocked for now? I am in a very stressful situation at the moment juggling work and DC at home and I don’t feel I can cope with any more of these messages, I really need to protect my own well-being. We are also moving home soon and I do not want her to know where I live. She has used my name and address in the past to attempt to fraudently get credit (adding as I don't want to drip-feed about the issues).
