I have no routine for the last 10 years and I'm genuinely feeling sorry and overwhelmed

I have no routine and maybe this is why I feel overwhelmed and somewhat I don't know fell into depression. Because like when you don't know what to do with your life and your not doing anything besides doing the same thing feeling the same thing and have the same thoughts but it's just life keeps adding more and more problems eventually you feel this mental defeat like Ahhh I can't do it.
