lost without her

5 months since she left and it still feels like it happened yesterday, broke no contact about a week ago and found out she is also hurting, i feel lost without her, ive been trying to improve my life but ive lost all my passion, lost all interest in things i used to enjoy, i felt empty before her and she bought me back, now im worse than i was before, struggling to find reasons to even bother with life anymore, i can’t remember the last time i had a good day, im just fighting the urge of begging her to come back to me, what am i supposed to do?
