Painful Flake

This girl seemed super down on tinder, I didn’t even mention her coming straight over. I asked what video games because she mentioned that on her profile and I was trying to build some rapport. After she wasn’t responding the day of, I called her at 7:30 to try and build some comfort, went to voice mail after 3 rings which meant she declined the call. After this she un-matched me which means she’s probably trying to block me from reaching her. How did it go from her trying to see me a day early to blocking me so quickly? Also this means I’ve lost all my good leads now and back to square zero in a 10 month dry spell, fighting hard to not sink into negativity. I'm nearing the end of my 20's with only 10 lays, only two of those were the type of girl I actually want and they both left me. I feel like I'm going to spend the rest of my life reflecting back on how I failed to get girls in my prime years. How can I combat this mindset?
