Hang out with friends and talk to people about it. Find some time for yourself, no matter how busy you are. Take a long shower or bath, put on some music, primp yourself, do whatever it takes to find some time for yourself.
This should give you a feeling of more control, instead of spiralling down with stress :)
2. stop thinking about how you re gonna deal with it and just organize everything. Organize what work you will do first, then second and like that. The easiest and most important first. The ones that are not easy or not that important, organize them however you want.
3. Prepare yourself for everything you re gonna do. It will make it much easier to do it.
4. When you re doing something, forget about the rest. Pick up the agenda again after you finished with it.
5. Leave the things that cant be dealed with for last. So, leave divorced parents out of your main focuses. Same as no privileges. Now on the other hand, these can be dealed with, but it takes much time and is not as important as the others.
Up to this point, you will see that not worrying about everything all the time can help you with your stress. But if you want extra conditioning:
Hi, Alexmaie. No matter what, you HAVE to make time for yourself. Whether you believe in the Bible or not, even it says, Love you neighbor as yourself. Which means you HAVE to love yourself before you can give all of yourself to others. After a while, honey, you will lose who YOU are. You'll get burned out and resentful of all you have to do. Sometimes you just have to learn to say "no" to some people and do something that will be good for you. You don't have to say it in a mean way. So say you have something else planned and you're sorry, but you just can't do it. Please take time for yourself and you'll feel so much better. I promise.
