I was 16 when I had my first child and I came across alot of negative attitudes from people both in and outside of my family. The general attitude was that I was going to be a crap mother and not cope and as I was not going to stay with the father either I was branded even worse.
But I am happy to say that my daughter is now 7 and a bright and happy polite little soul. I still managed to go to college and achieve 4 a levels while she was a baby and I am very proud of her and myself. We dont have much money but she has everything she needs food warmth love etc and neither of us suffer for it.
I am sorry I cant be much help about the benefits side of things I just wanted to show you some supposrt as I know exactly how you must be feeling right now but call your local jobcentre or CAB and I am sure they will be able to help. Ignore silly comments and enjoy being pregnant, the gift of a baby is not every womans right, so look after yourself cos you have been blessed x x
