Feeling Extremely Lame

It's only a little after 9 AM and the day is already promising to be bad for me. I haven't slept in two days. Someone I care about said some really hurtful things to me last night that I still cannot let go of. Then to beat it all I make a huge faux pas on a web forum by commenting on old posts in turn "raising them from the dead" (I swear I didn't know that this was poor etiquette) and the postmaster posted a thread specifically pertaining to this. I feel so embarrassed. I have apologized twice because I feel so bad for being unwittingly inconsiderate. I am fearful to leave my bed because what shall happen next? What else am I going to flub up? Who else will I disappoint? Is someone else going to damage my self-esteem and my spirit today by saying things that will hurt me? I am in a super dark place at the moment and I really don't know what to do. All these things that should be trivial are piling up and beginning to crash down on top of me. I am truly at a loss as to how to make things better right now! I am feeling extremely lame.
