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

Been dating for almost 2 years - I recently did something potentially relationship ending and just confessed last night.  Getting through the day today was horrible, can't keep my self busy enough to not be sad/depressed.  I have an opportunity to leave town and do an endurance event solo.  I'd be back Monday

My question is should I let her know?  She said she needed time to process and I know I do too.  This weekend is a festival in our town and I also want to give her the ability to go without fear of running into me.

I was planning to write a quick note and leave it at her place sometime tonight.  

Thanks for any help.
<bot>: I need to get out of the town my gf and I live in to sort things out, should I leave her a note/ let her know?
