Anyone religious? Sorry it's long

Recently I have strayed away from my God. Ever since, I've felt lost and always crying over stupid stuff I want to come back and praise him but he has taken so much away and I don't see any of the doors that are said to be open. I feel lonely even mute now then ever and I have no one to turn to. In the beginning he gave me to parents who didn't want me, I grew up with my aunt ergo I called and loved as a mother since being months old. He took her from me. Then let my family abandon me to foster care. Losing my baby (at a young age, which was probably for the best) then having my fiance walk out on me leaving me with no family to turn to. I'm 20 yrs old and all I feel is lonely. I need help.
