Quoting RissaTee:" First of all my boyfriend doesn't even want to have sex with me because he's scared that something will ... [snip!] ... looking lie a princess, not a $2 hooker! No one ever told me how hard pregnant would be! December seems so far from now!"
How old is your little cousin? As far as I'm concerned a child is only a bastard if one, he/she has no dad or two, his parents are not married. So I'm sorry but considering the facts that your boyfriend is still around and you are getting married next month your little cousin needs to shut the .... up. Again, sorry. No disrespect intended, well sort of.
Anyways, I'm sorry you're feeling this way. I can't relate because maybe it was the I was so excited to be pregnant but I never had a bad experience throughout my pregnancy.
Do you exercise? Maybe that'll help you keep the weight down. I used to walk an hour and 30 minutes a day and do pregnancy crunches and sit ups. Made me feel better about my self. It is sort of smurf'ish for your SO to ask you if you ever get full though.
Also, maybe writing will help. Try keeping a baby diary where you write to your daughter/son and post pictures and stuff for when they get older. I found that very fun.
