Just One Of Those Days

I'm having one of those days where I feel like I'm alone in what I do. I hate these days.....I soon end up feeling selfish about it all, and then can't figure out why I even feel selfish about it all. I guess I assume too much, or want too much.....but where is the line drawn when you need to ask for help...that sense of huimilty is never there without some selfishness....right? Not a clue here. Just tired of being confused about when to ask for help, when the right time to vent and to whom, and when to just shut my mouth and keep it inside.
