how do i react to my mothers moods

[c=003BB2][i]there's times my mum goes into a sullen mood with me, she is argumentative and instead of talking to me, she raises her voice....she has been like that right the way through my life...i have had psychological problems to cope with so my mum has had a stressful time with me....but i have had mental problems i've not been ''bad'' or evil.

at the moment the situation is i now live alone, and the mental health services are neglecting me....so my mum is helping me to support me and we're filing complaints too......my mum lives an hour away from me now but phones me every day...and when we talk i talk to her about my paranoia, anxiety and emotions...daily at times, and she gets short with me and raises her voice and is argumentative at times and that does not help me.....overall i have a good mother but she does get moody at times.......how do i handle it?

my mother is elderly now, should i just take it when she is not on best form with me and try to understand?[/i][/c]
