Can't lose weight!

Tamarra
I've been working hard on losing weights I'm 185 pounds and 5'4. Ever since I went to college I gain 40 pounds. I've been trying to lose this weight this summer but nothing is working. I get up I workout I count my calories. It's like everything I'm doing doesn't work. 
I'm doing it for me and also so my family can stop bringing my weight up. They make me feel that their opinions is everyone's opinion about me. 
Do you ladies have any weight loss tips? 
I really would appreciate the help.
