Am I allowed to Exist like this?

Now that the new semester has started I only have two courses, BIO 20-1 and BIO 30-1. So far they are fairly simple classes, the only thing I really have to do is memorize terms and make connections between the amounts of information that the teacher tells us to. I think it will be easy if I can find a good way to study and memorize everything, basically a semester to memorize the contents of an entire textbook. Do you think I can do it? I know University students do it all the time, so I shouldnt give up when I am only in highschool. I need these skilles for when I go to Uni this year, so I have to study as hard as i can to bring up my average. I can do it?! Now that I have so much free time..theres this akward tensions between me and all of my hobbies. I started finishing an oil pastel painting i started two years ago....i felt guilty when painting over the dried pastel marks...its really been that long since I have really focused on myself. Honestly, the whole time it WAS that DAMN PHONE T-T. Social media has ruined me, spacehey is a very simple platform and thats whats best about it, like the essence of the internet made into something digestable and pleasant. Anyways...i will start drawing, painting, reading, exercising, and sleeping more...to improve my health or something...Lately I have just been eating a lot since I am home all the time, its really bad and I think I need to buy a gym membership again. But the gym is disgusting and smells gross and I see people I know. its uncomfortable. However, In a society like this, seeing the sun and feeling the cold fresh air freeze my face is the greatest privilage I have been deprived of. I enjoy my mornings now.
