9 weeks and fed up!

Very fed up of feeling glum all the time. Even with taking anti sickness tabs from my doctor I'm still being sick. Today has been really bad, not even keeping water down. I want to be excited about being pregnant, but right now I'm miserable. My s/o says he misses the happy perky me. If I'm not being sick, im feeling sick. Totally unmotivated to do anything and drowsy from the tablets. I know I should be happy, but I just can't seem to cheer up.
