First of all congratulations on your weight loss, doing well!
Be careful as far as fat burners are concerned, most of them are gimicks are most fitness industry supplements are. Most of them comprise mostly of caffeine, too much of it will wear you out and make you feel tired. Be weary of any supplement that contain ephedrine hydrochloride- it can increase heart rate to dangerously high levels to those who are susceptible, increases your metabolic rate and dulls your appetite; which all affect diabetes one way or another. L-cartinine is a pretty good amino and shouldn't do you any harm.
If I were you I'd save my money and buy loads of decent healthy foods, new pieces of kit to keep me going- new pair of trainers perhaps for inspiration!
The absolute majority of fat loss is controlled by diet which should be your main focus.
If you look at bodybuilders, they get their bodyfat down to extremely low levels with mainly diet, then using drugs ('fat burners') they can get down to low end of single figures- so these are mainly used as the icing on the cake- diet being the main focus.
I also recommend going to sauna if you don't already, I find it's great for circulation, makes me drop water weight and makes me feel great all round- fantastic addition to exercise routine.
