Colic is terrible and as a mother pushes all your buttons - I felt like I 'should' be able to comfort my DD out of it and often cried myself so you are not alone.
But... it is not your fault, its just one of those things, some babies are just prone to it. So until it does pass (it will, I promise!) you need to have a coping strategy. For me, what I found got us through was:
-infacol, 2 squirts before every feed
-gripe water when the 'kicky legs' start, good for instant relief, Buy a medicine dispensing dummy in mothercare to make this quick and easy.
-buy an electric rocking swing if you can, with white noise on loud (used to buy us enough time to eat dinner).
-watch this and buy his book! Swaddling is essential
-i am bf dd and I used to feed her in a more upright position and burp her during the feed (every 5-10 mins) and between changing boobs to try and prevent wind
-be creative with your winding technique - lots of ways to try when you google it, we found the hula hoop action good, and a vigorous back rub over your shoulder, but experiment and find what brings on the burps for your ds. Dads are good at this so after a feed hand over ds and put your head down until the next feed when you can.
-agree what your DH what you can each cope with, for me I could take 20mins solid colic screams before I started to lose it. Make sure you can see a clock in every room, look at the time and switch with your dh through the evening.
But it will pass, so keep your chin up, you are already doing a great job. HTH
