Me and God

I am 25 years old. In these years I have been the product of druggie parents, born at 27 weeks and have had constant eye problems to the point my dr declared me unfit to drive recently because I can hardly see out of my right eye. I am the oldest of 4 and 2 siblings died before I was 10. At 10 years old I was seperated from my brother and placed in foster care and developed severe Bulimia w/ Anorexic Tendencies. By the time I ran away from the state at 15 after leaving work from my very first job to go across country, I had been placed in 73 different homes. I was having so much trouble with understanding God and I obviously became homeless which didn't help that. Eventually, I made my way into a shared room place at 18 and started bettering myself. I was diagnosed with pcos and subsiquently (sp?) had 5 losses before finally having my son but he has been having some complications. I guess my point is, I have always felt some sort of pull towards this God thing but how can I learn to trust something/someone who would let someone struggle for so long, who would take babies and siblings and loved ones away from family and make messed up families to begin with? How does a supposed loving God allow that? I am not athiest or anything I am honestly just wanting opinions here without it turning crazy. one adult to another, how does faith even work?... I feel alone and lost.
