What do you do when you lost your way?

I’m 20 years old and basically long story short literally all the plans I had for my future were ripped away. I am so very lost and stuck. Everywhere I look is a road block. I’m having panic attack that are waking me up at 2am, can’t sleep, can’t eat. Literally every area of my life has fallen apart (except I’m still breathing, can walk, and have a roof over my head) has anyone gone through this that can help? Advice?
