just starting but feeling a tad discouraged

I was at my biggest in August at 257 I have since lost 30 lbs but I sometimes feel discurraged because I once lost 90lbs and weighed 150lbs wich I loved but I got sick and then quit smoking in 2005 and had a baby in 2009 and got sever panic attacks after some stuff happened long story short i gained a lot and then some now i dont eat breads of any kind or pasta or rice i am gluten free becauae of celiacs and sugar free because diabetes runs in my family i dont do sugar artifical or otherwise i will have a tbs of honey a week at some point i get disscurraged because I now seem stuck at 227 and all i eat is a little meat and tons of veggies a tiny bit of fruit maybe some nuts but stat well below my set calories for the day and i exercise at least 30 mins a day most days i jump on the tranpoline for 1-3 hours with my daughter lol maybe i am just expecting fast results and it takes more time i dunno most of the 30lbs fell of fast within two months and then trickled for the last three what might I be doing wrong?
