You said earlier in this thread you had determination and passion so I am bit worried by the comment you're 'tired'. Not sure if you mean physically tired? Tired of trying?
Cricket is full of examples of guys who have been overlooked for years and years but have kept playing, enjoying their cricket, and working to get better. Think of Mike Hussey and Darren Lehmann for Australia who both had something like 10,000 runs in Sheffield Shield Cricket under their belt before they got a start with Australia. I am sure others on this thread could tell you examples from other countries as well.
And then there's Bryce McGain. He was told he wasn't even good enough for club cricket but actually played a test for Australia (he only played one and got smashed around a bit, but he still achieved something all of us could only dream about). Read this article
bryce mcgain | cricket with balls for some inspiration. And he has played for his state for many years.
The bottom line is if you believe you are good enough for county cricket then keep working to make it. You will get knock backs, you might be told you aren't good enough, and it will be hard work. But none of that should bother you if you really want to make it. All you need to worry about is enjoying your cricket and being the best player you can be. Do that and you'll give yourself the best chance to reach your goal.
Goood luck for the coming season.
