Hi Rebecca,
I recommend that you read the book "the Power of Now" by Eckhardt Tolle. Being a university student, i should imagine that you can grasp the philosophical ideas in this book. All we can ever really depend on is the present. The past cant be looked at in the present, because it is now past and the future has yet to happen, so there is no point in thinking of it. When you live in the present moment, there can be no fear of the future. So whatever you do, savour it, enjoy it ..For instance if you are drinking a glass of water be aware that you are lifting the glass to your mouth,. Look at the glass and see how pure the water looks. Say to yourself"what a wonderful glass of water" As you drink it, be aware of every sip you take. And be aware when you put the drink down. If the moment is not so positive, then surrender to the "suchness" of the moment. In other words every moment must be experienced , as it is Our minds sometimes play tricks on us: for instance a destructive PDoc in my past sometimes pops up for no rhyme or reason. I am aware that he is a thought in my head. So watch the watcher. Be aware of the thoughts in your head. I then say to him: Oh , not you again! and I redirect my thoughts to the present moment.
I Hope this helps you somewhat
