Seriously conflicted on baby sleep

On one side I am being told to sleep train from other moms and my doctor. They are making me feel like a sensitive, push over parent that won't help my baby learn to sleep if I don't just do the sleep training. There are so many moms that say "oh it just took 2 days and it was the best thing we ever did" Then on the other side I see articles, other moms and my MIL making me feel like if I do sleep train I am not there for my baby and I'm a horrible mom. They say "I could never let my baby cry." (Even just for 5 mins)

I totally get the agruments for both sides that I just can't make a decision and it's driving me insane!

My baby currently sleeps most of the night in my bed now and STILL wakes up every hour or two. My doctor is mostly concerned about me because I'm getting depressed from sleep deprivation. My husband sleeps on the couch and I deal with the baby all night and I go to work during the day. My husband is willing to help but most of the time I just deal with it since I'm already up anyways and I feel guilty if I am not the one up with her. We are EBF.

Help!? Why can't I just make this decision!
