I'm really sorry for your loss. Putting your all into this project I hope brings some solace but you need some support systems in place. It might be good to reach out to someone or someone else in your family and get a therapist. I find it difficult finding a therapist too but it really does help.
I will definitely buy your game and give it a try. It generally isn't a type of game I would normally buy though haha. Would like to keep in touch though, if you have a discord or something, let me know!
