Emotional right now :(

Autumn
So to start off I'm 13 weeks today. Yay almost out of that first trimester! Here is what is going on I've been such an emotional wreck lately and today isn't helping. Morning sickness hasn't calmed down it'd gotten worse today. I've actually been puking and can barely get out of bed. I work a full.time job and last couple of weeks I have even been putting in overtime which is not helping my tiredness but it makes the money. My husband is super supportive and does great at his job but today with how bad it's been I called in to work.and have felt like crap the whole time about it. :( I haven't called in here before except for days of bereavement with my grandmother and I've scheduled my doctors appointments with work so they know when I can't be there. Should I feel as bad as I do about having to take a day because of morning sickness?
