The sinus problems are awful. On top of your other ailments.
Physical health problems are so impactful on your mental health.
I think you need to push your gp for a solution for your sinuses - I know it's so hard to push when you're feeling so done with it all.
I really hope you can get on top on some of the physical problems it will obviously be be so helpful to your mental health.
In terms of simplifying, we don't make big plans. We don't organise too far ahead and we work out if we all need to go to stuff. If there's a family event we make sure that if they can't manage it or don't want to, that they know it's ok to opt out.
All family and friends know that they need calm and quiet (and not too much fuss or focus).
If they don't want to do anything, there is no requirement. We take the pressure off.
We have basically turned normal family life on its head and don't just do things 'because it's what normal people do'.
We're guided by them and, I feel, it's improved matters hugely.
I do like to get them out for fresh air as much as I can - I think it's very therapeutic but if they can't manage actually going outside, they compromise by standing in the garden for 10 minutes.
All that AND lamotrigine. I believe it has saved their life.
Do you still feel anxious on sertraline?
DBT is accessible via books too. Basic principles are acceptance and compromise.
I'm sorry for your childhood, when you have your own kids you just cannot understand how your parents could have behaved that way.
Can i just say, it cannot have been your fault in any way, they were just not capable of being any different. The people who love you now chose you and love you for you. It is all YOUR PARENTS fault and nothing to do with you as a person. It can't have been.
If you can learn to undo the way they made you feel (and still do, are they in your life now?), it will help you.
Keep posting.
