ok!
I can try to help a little
the first problem is 8. Qb3.
it lets the knight attack your queen again.
instead, Qc2 is better
Then, 12. g3.
it lets your opponent force your rook to move.
better was Bd3
14. Ne2 is not good either. it creates a 'one move threat' thats is easily blocked.
simple development is better
In conclusion, try to develop all your forces before anything else.
hope this helps,
