Have you checked out the LE diet? I would start there. It is basically 1500-1800 cals/day, 40-50g protein and 25-60g fat (depending how many cals, higher cals=higher fat). No snacking between meals and you need a good long fast each day so most of us skip breakfast and have a first meal around 11 or 12pm. I would drop the tea too and start drinking coffee if you can stand it. Coffee sways girl whereas tea sways boy. Being vegetarian is great for girl as well.
Sugar is ok on the LE diet but if you are PCOS there is a slightly different diet where you're supposed to lay off sugar. Do you know if you have PCOS? I don't but I am on the PCOS diet. Atomic could probably help you figure that out.
