Is anybody else so stressed out that they just feel like quitting?

im 16 ,and in 11th grade, and this year has got me feeling terrible. I work part time at a retail store(20-30 hours a week) along with playing three varsity sports. I am currently wrestling and my schedule is always so rough and i feel as if i never sleep enough, or have enough time to do things that i want to do. I am in some honor and AP courses and i feel as if im falling behind. I seriously just want to say screw all this and quit everything. On top of that i have an adopted brother from africa that i always have to look out for and mentor. hes only a year younger than me and has only been here for a year so i have to help him along with almost everything, i feel like this is all too much, for me to handle but i don't know where to start. Has anybody ever been in a similar situation that can help?Is anybody else so stressed out that they just feel like quitting?
Yes, I have been in a similar situation. :( My strong advice is to cut back on something in your schedule. Otherwise, you can be overloaded and breakdown. Like, don't be obsessed with getting A's and everything and doing so many other things all at once. Please, just simmer down on anything in your schedule. I strongly recommend it. Also, maybe ask for help from your parents with your adopted brother? I think you should tell them of your stress. They could help.Is anybody else so stressed out that they just feel like quitting?
Hey, I'm in the same grade as you :D

I'm stressed and I feel like quitting and I don't have half as many things going on. I think you need to evaluate your limits, you may have too much on your plate. The younger brother thing, just simply tell him to learn the same way you did and give him advice here and there, make him independent.

But honestly, I think you should drop one sport or AP.Is anybody else so stressed out that they just feel like quitting?
Sure and what I learned from it os if u do quite u wont know the end result or thr miricale will never happen
Man your life is amazing. I hate when you kids do this, you do not understand the meaning of life, happiness or love. First of all you should be so happy you have a brother that is so unique, and you get the chance to change his life, make it so much better than it was.

Go to a hospital and see patients who have worked so hard and still want to live so they can enjoy.
Go to a senior home and observe the amazing stories and how many hardships they have faced compared to you and they became successful.

Hey kid, never ever ever give up, and there is no reason to be stressed man you are so young and so much going for you. Wake up!!!

Stop making your life so hectic just stop some activities focus on what you believe to be most important, which in my mind would be your education, talk to your parents and discuss.
