I know it seems difficult, you may have to work crazy hours to make ends meet, even multiple jobs. But working long crazy hours can eventually tire you out and that's something you don't want to do. You will burn yourself out, you will get so tired you don't want to do anything.
I've personally have done this before and within the past 3 months too. I started college in the medical field, I drive an hour to school and an hour back home Tuesday-Friday. I work almost full-time hours on top of that as well. I was working day shifts then going into night shifts and then going to school. Eventually, with the help of friends and family, I realized I was burning myself out. I also had no time to actually sit down and relax or be a young adult and go out and have fun with friends. I also realized I became sick more or that I never felt good between running back and forth from school to work. It becomes a lot to handle and you shouldn't do the same thing to yourself.
I'm not the only one who has done this though. One of my best friends works multiple jobs and is a full-time student as well. I almost never get to see her because even when we do have days off on the rare occasion that we do, they are never the same day. I've seen her get so stressed out that she just has to have a breakdown and really who can blame her?
Working crazy hours and multiple jobs on top of being a full-time student can really take a toll on someone. She realized that she needed to cut back herself. We are barely in our 20's, we should be out having fun and worrying about school, not worrying about our part-time jobs that we won't even have once we graduate.
If you feel like you're overworking yourself and find yourself becoming stressed, don't feel bad to cut back your hours if possible. Everyone needs some time for themselves to be themselves and live their life. If you don't know if you are overworking yourself, please be aware of the signs such as having no energy, very irritable, grinding your teeth, low productivity, and physical symptoms such as sickness.
Honestly, you need your sleep and not like four hours every night that's not enough for your body. You need to take time off also, this will remind you that you are an actual person outside of your job. It really is okay to live life, have fun, as well as manage your job. There is nothing wrong with working, especially for the work-a-holics out there, but just remember to take some time to relax your body and your mind. Otherwise, it's just going to overwhelm you all at once till you finally just break down.
