One of those days...

It's been one of those days.  The kind where you can feel the tears behind your eyes and you know the slightest thing may cause the dam to break.  Nothing in my life has changed to cause these tears to collect.  Every now and then I realize that my life is not where I thought it would be at this point.  I've been to numerous family and friend gatherings these past few days and always somehow seem to find myself as the silent observer of the party.  I don't mean to be only an observer, but somehow can't seem to interject my thoughts into the conversations around me.  I just laugh and agree to all that is said, and for some reason feel like what I could say isn't important.  Friends are getting engaged and accomplishing tasks in their lives while I feel like mine is going stale.  I feel like I missed my chance to seize the day and am not sure what would make me happy at this point.  My life is great, but i feel like it could be more.  I just want to be happy but am not sure where this happiness is to be found....
