Discipline & Feeling Satisfied

Hey everyone,
I'm very new to this community and this is my first post. If I make any mistakes please let me know. I'd just like to breeze over what I've been finding difficult over this past year or so and hopefully someone could help me with my issues.

Just as the pandemic hit, I took the leap. I started my first business at 15 years old and the whole concept of running a business was very daunting to me.

For the first few months my happiness was through the roof I would wake up everyday feeling extremely motivated and virtually nothing could bring me down. All that quickly changed, I fell into depression and juggling school with business just made everything 10x worse.

Recently I've found that I'll open my laptop and just browse through Reddit or watch pointless YouTube videos instead of working. I have little discipline and whenever I wake up I don't feel satisfied at all. Don't get me wrong though, I love Digital Marketing and manipulating independant variables to see the knock-on effect on the dependant variable. I hope I can get some sort of help to boost my motivation. If you got this far thank you for reading, I hope you have an amazing day!
