Emotional stress

I definitely can feel the emotions all over the place. Getting off my video call with my first child (3 years old) and her father telling me they will be moving soon just broke me…. I fear he will never let me see her or let my daughter see her sibling ever… divorce was finalized about six months ago and he got sole custody of my little Luna!! I barely get to see her and it breaks me to pieces.. I feel like because I wasn’t in love with her dad anymore he’s using her against me for breaking up the family…. And now having another little one is exciting but I am so not trying to replace my first baby!! I just feel so alone and sad and I feel like I messed up everything and lost my chance to truly get to know my daughter…
