Ugh, stuck in a Rutt >_>

Guys, I have been SO stuck lately :(

*This* is my weight “loss” graph for the last 8 months… 

…my loss has become a literal WAVE of stall behaviour. Two weeks on two weeks off… 145-135 and back again. WHY CAN’T I DO THIS. I could have reached my goal weight right now!! What’s wrong with me >.<
