Going crazy......HELP

What do you do for a baby that is two months old and lactose sensitive and is on sensitive formula, and nothing helps. She's got bad gas, gas drops do nothing for me. Infant massage doesn't work. She literally cries all day and night. She Farts a lot and poops 1-2 times a day. Any suggestions. I'm going crazy and don't know what to to. I'm miserable and she's miserable. We aren't mixing well at this point.
