hashazma... check your measurements or judge by how your clothes fit to see if you have lost inches, even though you haven't lost pounds. Since you're exercising, you're gaining muscle, which burns fat... this is good, but muscle is denser than fat, so even though you weigh the same, you might actually be smaller...
You can compare muscle and fat to a rock and feathers... the rock would be compared to muscle and the feathers compared to fat. It doesn't take a very large rock to weigh a pound, because the molecules are packed very tightly (dense), but it takes a lot of feathers to make a pound, because they're light and fluffy - that's the way fat is - light and fluffy, so it takes a lot to make a pound.
When you start building muscle, you start packing the molecules more tightly, so you're actually getting smaller, but can still weigh the same.
Lifting weights builds muscles, but doesn't burn a lot of fat. You need, also, to do some aerobic exercise to start burning more fat. You could start walking, riding bike, swimming, zumba, etc. You can do some research on various types of fat burning exercises and find a few that you enjoy, so you can alternate them...
It's so hard but you have already lost a ton of weight! Be proud of that accomplishment. I would just stay on track- working your diet and working out. The weight will start coming back down! Do not worry!!
