Emotional basketcase

Sometimes I think I experience about 50 different emotions over the course of 10 minutes. I am stressed to the max with working full time and going to school full time, worried about my mom, frustrated with my daughter, helping take care of my 92 year old grandmother who is mostly blind and mostly deaf; dealing with frustrating clients, finances, being mad, being happy, being overwhelmed, being frustrated, being flat out pissed off like I am right now, then feeling sorry for being pissed off and being mad at myself for getting that upset, back to being in a good mood again, then the cycle starts all over. Sometimes I think my head is going to explode. Pretty much had a full blown panic attack and emotional meltdown driving home from work yesterday. Too much. Just too much. But then I tell myself, QUIT FEELING SORRY FOR YOURSELF!! THINGS COULD BE WORSE!! Ugh.
