Should i get back with my ex-girlfriend, who was a total ****** to me just for ?

i have not got laid in a while and i am being lazy, she really messed me up and i wound up on medication and was slightly suicidal and lost some friends (because i was intolerable) as a result of her. its been two and half years and i have managed to move on somewhat with other girlfriends and newer friends. but with th recession i dont have a lot of options except emigrate which im doing in october. i never did anything to her, when she left me etc........
