I had around the same age gap and like the rest of the western world, relied heavily on childrens TV to get through this bit! Like you I felt so shit but needs must. It's all about surviving day by day in the early months and your DS won't remember this I promise.
DD had severe reflux so screamed, fed and needed carried constantly.
There are no words that properly describe this feeling. Relentless, soul destroying, to your knees, type wearing. Awful.
One tip - don't keep feeding her one feed on top of the other when she has colic, big mistake, vicious cirlce.
To quote my pediatrician, "babies need AT LEAST 2 hours from the start of one feed to the beginning of another in order for their immature digestion system to digest, other wise they will be prone to colic pain"
I used to just about manage at it first if DH was in, walking her up and down with the hairdryer on to calm her until it was 2 hours. Id try to get visitors to do it if they were about during the day as the smell of me drove her crazy. If nobody was about, the hairdryer or tumble dryer used to stretch it out a bit (white noise, try different appliances)!
This went on for a few weeks until she naturally got used to it, then it was 3 hours. The colic/screaming/feeding died down loads. I just had reflux to deal with after that

Just do what you have to do and I promise, your LO will be fine. He is just a baby too and he is acting up because his world has changed for now. Go to the groups and sod what everyone else is thinking.
