Wow, Cirrus. I'm quite surprised at you being here.
You're always happy and stuff.
Well, fret not for non-official depressed HJSDGCE is here!
Now, you like your studies and is very tired at it, unlike me which actually dislike my studies and does it only for someone else. Well, it's hard to say on this as according to your text, you feel like you only have a few hours of usefulness to yourself which probably involves sleep entertainment, etc.
From the looks of it, this is a time based problem. Meaning, you have very little time for yourself. Now, a thousand other people would say that you should use your time better and to me, that is good. But, I won't say such. Sure, you can do it if you'd like.
But to me, you need to have a plan. Something that can run smoothly. Every time you go home, think what you want to do. You walk or drive your way home, think step by step of your free time plan. Divide the plan into segments of half hours. Like, spend half an hour cooking and 2 hours reading or something. If your plan is disrupted, then change th plan. It usually takes 5 to 10 minutes just to do this.
Even if I hate my studies, I don't have a problem with my time management. I've been doing it on my own for years now.
Plus, if your studies are hard, find certain patterns in it like similar characteristics from letters to steps and to much more. I have a terrible memory so I use this as a way to remember.
Made it based off autistic people and their ability to notice things we normal people don't.
