Conflicting Advice

I'm overwhelmed.  
Everything I read is conflicting with everything else I read... use pacifiers/don't use pacifiers, cosleep/don't cosleep, let baby soothe himself at the breast/don't be babies pacifier, expose him to daytime noises/put him in a quiet room, skin to skin 4-5hrs a day/baby should only sleep in crib...
I feel like I can't do ANYTHING right.  I'm a fucking failure over and over and over again all day & night, day in and day out. 
I don't have any instincts for this, no family nearby... I should be enjoying my baby - not crying and hating myself at every turn!!!!
