Colic baby

My 1 month old son is colic and cries literally all day and night. I am at my witts end and im losing my damn mind. I also have a 2 year old son who demands my attention and its so hard when you have a screaming baby to take care of ALL DAY AND ALL NIGHT. Im finding it hard to bond with my baby because im so exhausted and frustrated. Ive tried everything and nothing soothes him. Please someone help me...what can I do? My husband isn't very supportive or helpful so im kind of in this alone at the moment...
