i cant make up my mind.

lately i have been feeling very lost, about everything. I feel at times that i may have like some kind of mental imbalance in my brain. i cant make up my mind on anything anymore. and i always have doubts. Idk if its its the fact that i just dont want to make the wrong decision. or i just worry too much about everything. I am going to be moving soon. which makes things even worse.  It just adds to my stress and gives me even more things to think about. I feel as if i need to prepare for the move. but then my parents are telling me just live as we were staying. i am really confused about what i am suppose to do. i just wish somebody could throw a instruction booklet at me. and tell me this is what you are suppose to do. this is what you are suppose to think and this is how you are suppose to feel.. people tell me just stop worrying, just relax. BUT how am i suppose to do that if i dont know how to.
