I let people walk all over me constantly. I rarely stand up for myself and this morning is a perfect example. I called in sick this mornig (which I haven't done in the 4 months I've been there) and it took a lot to even do that. I was shaking while talking to my boss. She guilt tripped me because I was leaving them short. She called me 10 mins later asking me to come in just until she can get someone else. I said yes. I hung up the phone and cried in frustration. Why can't I just say NO!
