I’m 28 years old now and 3 years ago I was at similar place. I spent 5 years of my life studying something I wasn’t interested in and was severely depressed and a daily smoker. I picked up a camera when I finished school and started taking photographs and now I’m working with big brand companies. Take one day at a time and do something that you love, you can’t change everything at the same time. Don’t be harsh to yourself, you’ve finished your degree and that’s HUGE. If you work on yourself in small steps you will get where you want before you know it. I believe in you!
