It's only been a few months since the break up...I'd say wait another 4 months and you might start to feel a little better....as far as contacting her again...I don't think that's a good idea...I did that with my ex fiance (who was also a lazy, uneducated stoner)...even up to 7 months after breaking up...I drunk dialed told him I wanted him back and he told me no, and it broke my heart all over again...since than I've had no contact with him....I haven't thrown anything that reminds me of him away...but I hid it away from sight...since the NC (no contact) started, I've been feeling more and more like I've released the reigns on that one. There's also a website that kinda helped me called Baggage Reclaim....it's about mending your broken heart after someone unworthy (and if they did break up with you...than they are the ones not worth it) broke up with you...lol I mean it helped, but not 100%...but it wouldn't hurt to check out...
I give you props for not letting the breakup send you in to a spiral that could potentially cost you your dream job.
I think that's actually really cool that you wanted to help 10 people before posting your story...but if you could find the advise people need than use some of that advise for your own predicament.
Once you find "the one" and lose them, it hurts....a lot....than others will come along and some might be able to actually take your mind off that person, and others just won't add up to the greatness that was "the one"...but I guess it kinda helps to one day face reality and say to yourself, "She's not coming back and I'm better off without." than remind yourself of all the ways why you are better off without...I mean not like a list of negatives about her....but actually sit there and think of all the hurtful things she has said and done to you...anger is better than sadness when it comes to having your heart broken...lol...at least in my opinion.
