Probably just emotional from period

Just needed somewhere to vent and this is really only place I have to turn to... I've been trying to lose weight for years now and my boyfriend recently basically lost all the weight I've been trying everything to lose (we were both the same weight and both a tad on the chunky side) well now all I can focus on is how skinny and tone he is and how I'm still heavy and can't lose weight no matter the diet pills, exersize, how well I eat and sleep. I feel so self conscious when he touches me and how I'm so sure he's thinking about how fat I am..... thanks for letting me vent. Just feeling kind of down.
