I'm falling and I'm terrified

as much as i've tried to withhold myself, i think im falling.. not a deep fall, but a fall indeed..and this scares me..i'm caught in between - guarding myself and taking a risk.. im terrified of the things im not aware of.. im afraid that i'll get crushed.. im worried of falling hard, falling too deep .. i never knew that i could be terrified over such thing..im myself surprised at my own reaction..sure, people say its normal to fall, it is unavoidable sometimes..but still, i.am.scared!! to the extent that i cried..what's happening to me?? i've never imagined that i would turn out to be like this.. afraid of taking chances.. when things are doing great, this voice inside my head keep on telling me, "dee, all these sound too good to be true..step back a lil.. u cant afford to let urself get hurt..not again.." i guess its good that im still able to keep my feet on the ground, though i feel like floating.. but past experiences taught me a lot.. im constantly holding myself back.. i hope im doing the right thing..oh i dunno *sigh
