short cervix.. scared.. sad ..help!!

So I just left my anatomy scan I am 19weeks 4 days and the baby is active.. growing at the right rate and looks to be okay BUT I   found out that I have a short cervix... my heart is literally breaking I cried and cried and cried because the doctor explained that my pregnancy is now high risk and with my cervix being short I can potentially have a premature birth... I swear there's just always something but I know god will see me through, I'm just really nervous being that I'm a first time mom and I don't really know what to expect I'm just praying and hoping for the best, so right now I'm on my way to the hospital they have to monitor me overnight and then tomorrow I will get the procedure done ..which the doctor explained to me is the cerclage ..my boyfriend and I spoke and we figured that was the best choice for us, he has been nothing but supportive and is assuring me that all will be okay and I love him for that..I'm just exhausted from life and the news ... all in all I just want a healthy happy baby... but I can't help but to be worried.. but my baby gave me a thumbs up today and that made me feel that everything would be fine.. but in this place called life you just never know! has anyone experienced this? And if so can you please share your story... I'm posting anonymous because unfortunately ladies on here can be kinda vicious and right now I can't take that.. thank you ladies in advance ❤
