Opinions ?

My therapist suggested I have a steady routine for stability but how do I stay consistent ? I’m not good at writing stuff down and my phone is like another helpful device for me. What can help keep me on track ? Phone apps, more routinely things, anything ? And what else could I incorporate into my routine food wise, health wise, hobby wise etc ? I’m a vegetarian and i am on a lot of medications that will block my chances of heavy exercise. I can’t sit still for too long & it’s hard for me to concentrate. How do I keep my life from getting too chaotic or unstable ? How do I make sure I stay on top of my medications, appointments, life, bills, etc ?
