Struggling with Cannabis Use and Personal Expectations

Hey, Let me tell you about the predicament I got into this year. I started smoking cannabis last year, and I had nothing but good experiences. I used to be in a marching band in college, I had scholarships, and I was feeling happy. Recently, I lost my scholarships; I’m on academic probation, I’m struggling to find peace with myself, and idk why. Maybe it’s because I’m never satisfied with myself, or I had high expectations my parents held. Now, my family is not really looking at me the same, and I get reminded that all I know is how to mess everything up, and as you can see, my username tells my entire situation. I’m also bad at budgeting, my social skills are far from normal, and I feel lost. Idk what to worry about the first bc it’s messing up my mind. What should I do, and what should I worry about overall in life?
