I suggest you take a time out. E.g. take a bath, listen to music, do yoga, exercise, watch a movie, go out with friends, basically anything to take your mind off the stress. Make sure to keep things balanced and organised. It seems like your doing a lot of things at once and your not balancing your time out properly - you should keep a diary or journal to schedule things that need to be done. Space these out so that you don't have too much things to do in one day. Also, write reminders, if it seems like your forgetting a lot of things do it because it helps you remember but also not burdening you because you don't have to actually remember since you've written it down. Also, avoid studying late at night because it is probably the main factor why your so tired all the time. Talk to your family about the reason why your stressing and maybe they can help your out. So, look, everyone feels stressed at some point in their lives so just remember - keep a schedule, sleep at least 8 hours, exercise daily (even just a little), be more organised and eat healthy. Btw you can talk to me anytime if you want, if there's anything else :) Good luck.
