Lost passion? Lazy?

I feel that i have lost my passion in life. I cannot found any thing that make me feel interested. Since the first day i come back to Kuching,i just feel tired, and now already second month but i still tired. Don't want to touch my book, my assignment, my FYP and even lazy to go out. Feel tired to go to class, tired in manage relationship with people just tired with everything. Is that i really lost my passion or i just find an excuse for my laziness. Hope that i will recover soon, i should not and also can not live like that. I still have to put effort for my great future. Come back chinyee, come back my heart and soul.
