How do I heal from my Miscarriage 😭

So I've been balling my eyes out since Wednesday when I found out I was pregnant but yet miscarried... I have never experienced anything like this in my life or felt this kind of pain before & I'm trying to stay positive because I do already have beautiful 2 year old baby girl but in the same breath I feel miserable because me & my fiancé were so excited and looking forward to having another little one running around when we've been trying to conceive for MONTHS... I try to remember that there's always someone in the world that has it worse then me but how do I cope with this?
