Re: Feeling like a failure
You are not a failure. You are doing your best and that is all you can do. My LO was 5 lbs 14 oz at birth and 5 lbs 4 oz a week after birth. We also had lots of trouble early on (for different reasons). I had to supplement but always offered the breast first. I also pumped after every feeding to help build supply. I can't imagine doing that with other children though. It is not too late to BF. FWIW, I know a mama who only bottle fed BM for weeks and was eventually able to nurse.
Have you thought about contacting your local LLL or a LC for help with the latch?
