I suffer from pretty heavy PTSD. What does this mean? For me, I can sometimes get reclusive and slightly agoraphobic. HOWEVER, I've realized that when I have someone special in my life who will kidnap me against my will and force me to do things outside of my comfort zone, it snaps me out of it. I know that sounds heavily co-dependent, and probably is, but I recognize this and am okay with it.
But back on the fun side of things, when I'm getting out of my shell, I absolutely love to get out and do things -- whether it's dancing, karaoke, brunch, hiking, exploring, or plenty of other activities!
