sorry about the underboob. so i used to be 160lbs i maintained that weight untill i got kicked out of my house and moved in with my fiance. i gained 75 lbs within the past year. ive been trying to accept my body the way it is but i just cant. ive been in mexico for the past month and for the first time in 5 years ive started losing weight. im still chubby and i still have a long ways to go but im finally feeling good. my fiance is helping me lose the weight. i wanna go down to at least a medium, im a 1x right now. if anyone has any advice id love to hear it.
