Well done to you! A FIRST is incredibly hard to achieve, and you should be chuffing proud. Bollocks to anyone saying you shouldn't be boasting.
Why on earth are we made to feel bad for celebrating success?
My daughter got a first, she has completed a masters, and at 26 y.o. has a job in middle management that pays £44K and this is not even in London, it's over 60 miles away! Her B/F has inherited £125K from his grandpa, and they have put £75K of the money down on a house, and are going to NZ and Australia in November. They have have a car each, and have learned German together (in 7-8 months,) and can both play guitar and have written and recorded several (REALLY good) songs. They plan to get married next Spring... 
I have not told anyone any of this this, as I fear they will think I am bragging. Especially as amongst the people I know, someone has had their house repossessed, someone has had their son drop out of uni, someone I know has all 3 adult children still living at home, someone I know has adult children who can't get a job (a few won't even try!) and I feel it would be rubbing their nose in it. So I don't tell anyone about my daughter's achievements and good fortune. 
All it is though, is my daughter has worked incredibly hard for everything she has and like the OP, she deserves it ALL. And so does her lovely fella! (The inheritance is a nice bonus... but she has worked for everything else...)
I am really chuffed for you OP and think you should be very proud. Especially as you did it whilst raising a family!
