I need help

its been maybe 2 months since I and my ex broke...it was for the most silliest thing, its such a long story but in the 6 months I dated her, that was the best moment of my life but I somehow ruined it, I didn't realize it till now but she was my everything, I confided in her and she confided in me, she saw me through my worst moments and I did the same thing, we both cried together one time and I never cried in front of any gurl. Now we've broken up, I believe she moved on and now I'm in a situation...I have no one I could really pour out my heart to....I'm fucked up, I miss her badl y....how does someone get so attached in 6 months...I don't know it's hard for me to just move on...it's just too damn hard even how hard I try...I'm just ughhhh not my self anymore
