My aunt is in her early 50s (i'm 39) and we recently reconnected after 20 years. When i was a teen I really got on with her and she was 'normal'. Since reconnecting she has told me she has BPD and CPTSD and I really wanted to help and be in her life. Six months on and i'm struggling to handle the relationship. She says things to me then denies saying them, we get on well then she blocks me for trivial or unknown reasons. She constantly changes her mind with everything and wants help such as changing her rooms around that involves drilling, filling walls and moving furniture around. She is never satisfied.I am an advocate for her benefits as she isn't allowed to phone up etc due to lacking capacity. She keeps changing her name on there and other places to the point where I don't know what name she is going by. I help with her post and saw a new passport in yet another name that is costing money all the time. She just expects me and her boyfriend to deal with all this but I honestly can't. She's not the same woman I knew before. Trying to discuss it results in me being blocked or her saying she can't help it. She needs a carer but social services can't help anymore either. There are so many other difficulties but not enough time or room to post here. What do I do? When she's ok we get on great and she's a fantastic aunt but all the change is affecting me.
