My mum has been my main support for me and my children. My Ds has Asd /behavioural problems and anxiety where he's not left the house or been to school for a year. I finally have services involved to help after fighting a long time. Mum would come to all the meetings, help with meltdowns etc. She was my rock. We spoke several times a day.Two days ago she left a letter for my dad and one for me. She's walked out. The letter was very vague, but said she'd turned her phone off but would be in touch. I has spoke to her best friend who wouldn't say much but that it was permanent and she was starting a new life. I'm devastated. I feel betrayed and and grieving. Don't know how I will manage without her. I'm angry she could do this without explaining to me. If she's met someone I really would have understood but how she's gone about it I'm broken. I have to get my Ds to vulnerable learners next week for a few sessions and I really need her support. I have no friends as I'm isolated due to circumstances. Sorry this is so long, just need some advice and supporting words. Thanks
