I am trying to lose weight after having 2 children.. but it seems nothing works now. any help?

i tried everything. atkins, no fat, less calories, working out. but it seems this weight wont budge. at all. i am 5'5 and 165, but i dont look like it. no one believes me when i say it. 3 years ago i was 130.i still wear the same size clothes! all my fat goes to my lovehandles. it sucks! and i cant lose any weight at all. should i go to the dr and get diet pills? how fat do you have to be to get them? i am desperate to get skinny again.
