My Legaltech Startup has been failing miserably and idk what to do ( I will not promote )

I'm at verge of shutting everything down and quitting the startup game permanently I've been told this advice countless times build something people want now what am I supposed to do when businesses outright don't want to try out my application I believe I should quit the startup fantasy and start working a 9-5 as much as my ADHD brain hates a regular old job every day I wake up and hate myself for dropping out of university and building my startup, my family hates it, I hate it and I Know if I give it X amount of time it will eventually work but I need it to work now to survive anyone got any advice ?
