How to not live day by day?

I use to be suicidal since i was 13, i am now 20 and am no longer suicidal but due to all the therapist and stuff i was taught to just live day by day, idk how to plan for anything or have any self control because i ONLY do things that bring me joy, i find everything else useless and idk i just need some advice on how to live normally now that i am free of my thoughts lol
