Pregnancy Feelings... Is this normal?

I am a few days over 17 weeks pregnant. I feel so guilty for feeling bad during this pregnancy. I am always crying, sick, tired, and mad. I just want to grow this baby inside of me and deliver. I know that each child is a blessing and I feel horrible for not having positive thoughts. I am excited to have the baby, and I am elated to bring another child into this world. I can’t stand who I am as a pregnant woman and what it is doing to my body, my mind, and my family. I hope that this is not who I have become and just pregnancy hormones getting the best of me. I hope that my son and this child do not remember me like this. I hope they can look back and smile to their memories of me. I just don’t know if I can give them those memories. I have a wonderful family and wish I could be grateful and positive. I can’t. I am so unhappy it hurts. I hate myself and wish I were different. I cannot change no matter how I try. No one seems to help. It’s just me trying to stay alive for this unborn baby. Why do I feel like this and why can’t I get rid of it. I can’t stop weeping from the pain.
