colicy baby

I was wondering if anyone has any tips for helping colic. I have tried everything I've found online and they only help for a very short period of time (changing my diet, warm water, walks, swing,holding positions, gas drops, etc). my little one cries for 5+ hours straight every afternoon and nothing can soothe him. my husband works 14 hour days 6 days a week so he cant help much. he does help me with nighttime feedings if I pump. I'm more upset that I can fix what's wrong than anything else. yesterday I literally cried for over an hour with him because I cant help him and I feel like that's my job as a mother. I love my little boy but it kills me that I cant make him happy for anyone else with a colicky baby remember it will get better eventually! you're not alone even though you may feel like you are
