I feel like I'm the worst mom to be...

I've wanted this for many years and now I'm pregnant with these two beautiful healthy babies. I feel blessed bc we lost 2 before conceiving these twins.  I recently learned that my cervix is short and have to be on bed rest. Doctors have been great by providing everything to keep them in place. I'm 23 weeks and 4 days. This has put on an emotional roller coaster. I'm so nervous, scared and worried etc... I'm starting to think if I've made the right decision about having children in my life. Maybe I'm venting, I don't mean to complain. I need to continue to have faith and stay strong but I feel like I'm weak as water right now.
