Having a hard time eating

I’m 5”4 last I check 145lbs

I’ve always been skinny fat kinda toned. But since Dec since my baby brother was murdered. I haven’t had it in me to eat anything then alone workout.

I’ve been surviving off frozen pizzas, chicken nuggets and my hyper fixation food pancakes. I’d say I try to eat once a day.

I think it’s important for me to say I have that fun Autism-ADHD mix.

And I know it’s probably depression stacked on top of winter depression on top of ED.
I need some advice to get to eating more…
