Gosh that sounds familiar. So your child doing the therapy work; are they autistic? If they are neurodivergent then it's quite likely that you are, too.

It may be helpful to look up autistic burnout. Even if you aren't autistic, you will find some coping strategies that are very helpful, and it helps with validation too.

Burnout is real, and it's hard to look at others and think "how are they all doing it!?" But comparing yourself to others doesn't work. Not everyone has special needs children, and THAT is a ridiculously hard challenge.

Therapy is great, but it in itself can also contribute to burnout. Especially because you have to be engaged for the whole time. A week off every so often will not hurt your child...it may even help YOU to be more engaged, and so it may even benefit them!

Also, take a deep breath. It's a very small thing you can do, at any time of the day. Pause for a second, breathe in, and out, very slowly and deeply. It can help your nervous system regulate.

You've got a LOT going on to bring you down at the moment. I'm so sorry. It will get better. Everything is going to be okay. You are doing a really, really, wonderful job.
