Should i start reta?

for context i am 5'6, 175 lbs F 20yo. I can def stay disciplined and lose the weight naturally bc i have discipline in other aspects of my life but i have constant food noise, my body responds well to weight loss but I just get so stressed thinking about where I am right now that it takes away all motivation. I wanna take reta while being active and eating well too kind of speed up the process, and when i've lost the excess fat and when I am just not overweight anymore hop off it and start strength training etc.
