a bad feeling

i've had a bad feeling these last couple of days.  i'm not sure, but something feels wrong.  i feel the need to ask if things are ok.  i hate being needy and wanting that reassurance that things are fine.  that's not a good characteristic to have.  i have to struggle to go through the day like things are okay.  i keep telling myself that things are fine, but the "self" talk isn't doing it for me.  the reassurance has to come from an outside source.  i've been through this so many times before.  i really hate what i'm feeling.  i don't know what to do about it.  i don't know how to stop the cycle.  :(
