im sorry you are going through this, the morning sickness will pass. we'll be there if you have any questions or concerns. i know you say you dont know if you want to have a baby, but you are already pregnant. It will get better, I hope you have a happy, healthy 9 months :)
Well honey no one can tell you what to do. All i can tell you is...it gets better, and it's all worth it in the end. Your only options are: keep the baby (who you WILL come to love and enjoy), adopt the baby out, or have an abortion. I do know that if you have an abortion because you feel "too sick" you will probably regret it the rest of your life. You can't take that kind of decision back.
Trust me...you're in the worst part of the symptoms right now. In a few weeks your symptoms will get better..and then a few weeks later you'll find out what gender your baby is, and feel him/her start to move. When your little one begins wiggling around in your belly I bet you'll fall in love.
Did you try to conceive this baby, or was it a surprise? Are you feeling resentful because you feel sick? You should consider talking to a therapist about how you feel...don't make any big decisions for at least a few weeks; see how things go. Your symptoms SHOULD get better in a few weeks. If you're this sick your doctor can prescribe safe medicines for you to take to ease your symptoms as well.
Please just don't make any decisions yet. You don't want to make a decision you can't take back.
