Would you keep trying if it's still as difficult as it used to be? And if you're not even sure if it'll get better or if you'll achieve anything at all?
When it comes to something you really want, I completely agree with perseverence in the face of hardship. But blind determination on the other hand.. is it worth it? Is there a point in it? Just because of a "what if" and an "in case". Is that mirage so attractive that you have to put yourself through uncomfortable situations? What if the end point is just numerous uncomfortable situations that won't improve? What if you just weren't made that way?
Maybe it's time to realign myself to my old life. What's wrong with not making the effort anyway? Maybe nothing.
