<human>: Can you succinctly summarize the text in 1-3 sentences?

First an explanation as im new to this (first post), i'm a long time lurker and would probably have remained so but I was dumped on Friday ending a 4 year long-distance relationship and prompting me to man up, gym up, and just be more damn social and that includes the grand old internet. 

So here is where my question stems from reddit...this happened suddenly and destroyed the plans I had made for my life, wanting to move and be with her and build my life around that. now I am quite young at 20 and im glad im an old soul enough to realise shit is gonna hit the fan in many aspects and you have to be prepared to deal with it which I am.

 but holy crap I had started to prep moving colleges and states and im at a small crossroads of life on how to take this all now. so reddit my question stands. what moment in your life made the course of your life changed it from what you had planned?
<bot>: had a plan for life and it literally got....dumped on (YEEEEEAH!) what moments in life played out like that and how did you manage?
