I’m 16 and recently got fired from my first job, I have no idea what to do my parents don’t trust me I’m lost

I’m 16 years and was recently just fired from my first job at an ice cream parlor because I admitted to my manager that I had been consuming marijuana because I thought it would help my continuing depression and deep anxiety (I have ADHD which I take meds for) , I take full responsibility for my actions and it really took me a while to realize how destructive weed can be to my life. I’ve lost my girlfriend, my job, privileges, and my parents full trust. it’s been 2 weeks from that incident and I guess I’m getting back on my feet but I’ve never felt so depressed and lost in my life. I’ve been getting back into the gym and my sport but I feel like I have no direction in life and almost like I’ve ruined my future in this short time because of my ignorance. I haven’t talked to any of my friends since the incident mainly because my communication is restricted goal anyone else “for my safety” I no longer have access to my bank account, phone, or my room. I’ve been sleeping on my couch for these 2 weeks even though I’ve told my parents I don’t have anything in my room that’s dangerous. It’s all my fault and I understand that but I want to move forward and fix my life for good.
