[Advice] How can I improve my life if I feel like my life peaked in high school?

My high school days were marvelous. I had so much energy and motivation to do things. I woke up at 6am everyday for years without a problem. Most of the time, i was excited to go to school because those were fun times. I graduated high school in 2020 and most went downhill. I began doing everything online and i have no drive to look for jobs unless they are remote. I have never been this down bad before. i miss who i was before the pandemic. The only good part post 2020 is i physically look better but thats it. I was happier in high school. Idk life just seems so boring and bleak now. I want change but idk where to begin. I do college online and i have a home gym. I also have a very messy sleep schedule.
