On being pregnant and first time mother

Pregnant....scary... uncomfortable...a lot of stuff are going on inside my head... lots of mood swings.. sometimes I think I'm going crazy... there are times I feel so bored that I dont know what to do... always exhausted... these are just some of the stuff that I am experiencing with my pregnancy and being a first time mother...or rather soon to be mom... On my first trimester everything was a mess... I been in and out of the hospital due to the reason that the food I'm taking will not go into my system... even water will not stay down... I've come to a point that I'm so scared to even eat.. because I was so scared that I will throw up all of the food again... Im on my second trimester now.. i dont have lots of nausea but Im still scared sometimes... If there is such a thing as pre partum depression, I think I am having it. My second trimested is almost over, now that my 3rd trimester is getting near, I am getting more scared for the delivery and for the welfare of my baby, and what will happen... I'm anxious for it to go out... because right now it is very uncomfortable... I know I'll get over of this anxiousness and the scary part... but as my delivery is getting near it feels like its not going to end. I just hope that delivery will be okay, baby will be okay... and I hope I could be a good mother...
