Help! stuck in a plateau

I hate this I had my surgery 2 yrs and 2 months ago..I can't seem to get below 190..I don't know what else to do, I've increased my protein and water..If I increase my water intake anymore I'm going to burst!...and also tired of everyone telling me you don't need to loose anymore...I'm not ungreatful at all....but when I look in the mirror I still see the 320lbs. woman at times....the clothes I want to wear I won't since I have this little beely that shows...I exercise and it doesn't tighten it up...I need a tummy tuck but can't afford one.. it doesn't look attrative to let it all hang out...lol ...I just would love to see something other then 190 on the scale....also looking for new friends who understand what it's like to go thru this surgery...please don't pity me...just having a down day...
