Dealing with Burnout and the "Fear" of Growing

My e-commerce apparel brand is going to be hitting its three-year anniversary in two months, and I feel incredibly burnt-out. I started my brand when I was 15 years old, and now, as a freshman in college, I've made revenue of well over six figures. In the year 2020, I was able to make $80,000 and it made me feel incredibly ambitious. I started to have dreams. I started to think bigger, and I knew this was something that had so so much potential. As a child of Asian immigrant parents that didn't even finish high school, I knew I had something precious in my hands and I had one goal in mind: To make my parents proud and to let them be able to retire early. To live in New York City in my 20s.However, as 2021 hit, I started to feel burned out. It felt like my business was growing too much for me to handle. I couldn't keep up with replying to so many customer emails. I had no time to constantly be designing things (I started to run out of ideas too) and had little to no knowledge on supply chain management and timing things correctly. I knew nothing about marketing, and as much as I wanted to hire people, I had no idea how. I had also been working my ass off in 2020 for the success that I reaped that year, but as time went on, I needed a breather. I needed time for myself in 2021. It was my senior year and I wanted to enjoy my final year of high school. I started to slack off and became unmotivated.I feel like I killed my own business. Everything was too much for me to handle on my own and I didn't know what to do. I haven't released anything in months, and I'm rapidly losing followers on Instagram. I just feel so burnt out. I don't have any new designs to produce. I'm terrified of making $25,000 transactions. Everything feels so foreign now that it's on a broad scale. I don't know how much of each item I should be ordering. I don't know where to find good suppliers that won't rip me off. It feels like everything around me is collapsing and as I panic more, it just makes things worse. My dreams feel like they can't be a reality anymore. I can't help but feel incredibly disappointed and frustrated in myself knowing I could've worked harder.With this, I'm asking for advice from fellow entrepreneurs or anyone that has been in the same situation as me.
