How awful for you when my little boy had colic it was awful i could set my watch to when he would start crying midnight, and did not stop until 7am then my little girl would wake up about half a hour later this lasted for 3 months. I was completely exhausted, i tried to put him in his cot and leave him, but it just made me feel so guilty i sat in the lounge crying my eyes out breaking my heart feeling like the worlds crappest mummy. I really hope you can get some help soon if i lived closer then i would offer to babysit take your baby for a walk, or drive, so you could have time off make some dinner, or have a sleep, or simply have time to yourself. Take care.
