Hi op thanks for starting this thread it's quite informative
I'm mum to 2 kids, DD 14 is like you but so sensory with Misophonia and misokinesia she cannot attend a normal school but goes to interhigh
DS is dispraxic and their dad is an obvious missed Aspie with anxiety
DH has always worked so it can be done, works as a specialist type number cruncher, if I told you more it would put me but rules are his thing!
With DD we know she will have to develop her own career from home, she can even do her degree from home if necessary but she has been brought up with the expectation that she will have a career
Self belief plays a huge part, we have never told her that she can't but encourage her to research what she can do
Right now you need some careers advice and honesty with yourself, perhaps even some counselling
look at what you've already achieved and aim where you feel you can go, break it down into small steps and start walking
