Hi Ula
I've been around caring since my sister was born over 60 years ago, and I can't remember a time when I wasn't in the caring world. For 21 years I worked at a Carers Centre in my area. I have two sons with autism (one is diagnosed, the other refuses to consider diagnosis and has additional mental health issues), and my wife had a spinal cord injury almost 8 years ago and has to use a wheelchair outside the house. My Mum is in a care home as she has dementia.
You can see why I understand the need to take care of yourself first!
One thing I used to do regularly with groups of carers was encourage them to look at their successes: most carers struggle with this because they see the struggle first. That's understandable, but it leads to depression. You've listed some of your successes in your post.
Your daughter is gaining independence. Think about the things she's learnt to manage for herself in the last year. Who manages her bills? Plans her meals? Cooks her food? Who taught her those things?
Your daughter avoiding hospital during that time is a huge achievement, and there's no doubt that you were very much a part of that success.
You've every right to be proud of yourself.
