Why Am I Suddenly Feeling Depressed ?

i was boring when i just spend my off day with sleep and watching movies. and having to remain in bed for a day or two. i am not sick – not really. i am just feel theres no one can makes me happy.. i rather choose sleep then talking with peoples,  theres must be something wrong with me.. I'm usually a nice person, though I have had my moments in life where I have been mean to others that don't deserve it... I feel physically exhausted and my mind has never been so focused in my life... I just want to know am I crazy or is what I feel basis something that could be honestly natural ?.  is there a way that I can figure out how to handle these things? I always worried about something but I do not really know what i am worried about..


but, actually.. i have one thing that bothering my mind.. but its just the one from all those things that i dont know it is..  its  most painful thing because i losing myself in the process of loving someone too much, and forgetting that i am special too.  Yes, i help others; but i didnt help myself.. In life i realize that there is a purpose for everyone i meet.  Some will test me, some will use me and some will teach me... and i do really love this one guy who always Test me, Use  me and Teach me to being freely with my self.. i do love him so much... but unfortunately he dont love me back.. just tired of doing the same things to win his heart over and over without take a break..
