kellie,
its perfectly normal to be going through a whole different range of emotions at this time. I found out i was pg in October, and mc'd in december, so im at the same place as you are. I still cry most days. Especially when im around other pg people. My SIL announced she was pg just 2 days after my d&C, and she is 2 weeks behind where i would have been, so i have a very hard time thinking about her or being around her.
I have found that coming here and venting has been so very helpful.
Im so sorry that your family have not been very supportive, but the girls on here are all wonderful, so please use this as much as you need to.
when you do fall pg again, ti will be extra special..thats what i tell myself!
