Right now, I am very confused about my future, about life. Feeling quite inadequate every single day, wondering how I'll fare in my parents' shoes someday. Regretting not reaching out to others more often. Regretting. That is what I'm doing right now.
My best advice would be to find an activity that will occupy your mind, and just try to accomplish as much good as possible with the time and resources you have available. "free time" is something I try to avoid having for that very reason. Staying busy gives me purpose and purpose gives me motivation.
