<human>: Can you give me the gist of the text in a nutshell?

So recently ive started to realize that i may be over attached and obsessed with situations i go through.

Example: This weekend i went to a concert, and for the first time a girl started dancing with me. It was amazing and i got real into it and was having alot of fun. Eventually the girl drifted off and was dancing with another guy. Now i didnt know this girl, only danced with her for like an hour( it was like grind dancing not just like dancing around, she was like grabbing my hands and rubbing herself with them, sorry if im over descriptive with that, it helps to get all the info out), and i realize that i would more then likely never see this girl again in my life(im from michigan and the concert was in toronto) but instantly after she left i kinda got depressed which felt weird at the time. Later that night she was all that i could think about and same with today, to the point where im actually having mini panic attacks and depression over the fact that ill never see her again.

This has happened with other situations alot lately where it seems i cant let things go or i over think and obsses over things for way to long that it starts to hurt me mentaly and emotionaly. Im starting to feel like im going insane because there is no reason i should feel this way over things like this. I was just wondering if this would be considered partial ocd or not and if anyone has any tips to help me get over stuff faster and let things go. With the above example i started to feel creepy cuz i was looking through instragram for hours trying to find pictures of her from the concert to try to find out who she was. I finnaly did find out but i thankfully was able to keep myself from adding her on facebook or messaging her. Like i said above this has just started happening recently and its starting to worry me about my mental state. Any sort of insight would be greatly appreciated.

Sorry for wall of text
<bot>: I cant seem to let things go and i over think/obsess over situations to the point where i knew a girl for an hour or 2 this weekend and am now depressed that ill never see her again. Any advice?
