Sometimes in life, it feels like everything is pouring down on you at once. From what I am seeing, it seems like you have a lot on your plate. These are all important exams which will determine a major part of your life. But there are several things you can do.
Firstly, it is important to plan your life out. Since you have such a busy schedule, it is important to plan almost every second of your life for the next few months in order to be able to properly prepare for everything. Having a daily, weekly or even monthly planner can help you evaluate what you have to do and when you have to do them. University applications have deadlines that you are pressed to meet. Putting down these deadlines and crafting a few deadlines of your own could be helpful. Fixing the dates for studying can help to ensure that you do not procrastinate studying for these important exams. Also, putting down things that you need to do-like buy stationery for the exams- can ensure that you do them on time.
It is important that you talk to people. Keeping these feelings bottled up inside of you can be dangerous for your health. Your teachers and parents are only being hard on you because they know how much work you have to do and they want to make sure that you get all of it done. But if you still feel like they are pressurizing you too much, tell them how you feel. They will most likely want to assist you in any way that they can. Also, you may feel that everyone is out to get you because of a few unrelated incidents. Talking to your friends about these problems can help you get different perspectives of the situation. If you feel uncomfortable talking about your issues to someone, writing in a journal can help. Expressing your feelings is important in helping you not to get too stressed out.
Lastly, it is important to pray. Every decision that you make should be carried to the Lord in prayer. It is only God that knows what is good for you and only He knows his will. The will of God must be at the back of your head. The Bible says that all those who love God should ask and they shall receive. Strengthen your relationship with God through prayer, meditation, Bible studies and righteous deeds. Pray with friends for the Bible says, when three or more are gathered in my name, know that I am with them also.
