Hi Lizzie
There should be some options for someone else to care for your daughter.
I feel the same way, alone in a new city, distancing from what I considered friends, etc. after the breakup.
After 5 months I am still struggling with the turn of events, but this guy was not capable of loving me or caring for me so... its much better to be alone. Better not to lose time or energy, for me it was like throwing everything to an endless pit...
Hang in there, hugs!
