If I were in your situation with the knowledge I have now, I'd say, in order of priority

1. Make sure you understand and accept the position you're in

2. Try and understand that changing ourselves is done 1 thing at a time

3. Exercice (very important)

4. Write down some realistic goals and set up a few hours each day to work towards them.

Don't beat yourself too much, enjoy the little things in life (for me, beer, eating, and coffee), and stay kind with your fellow humans
