Just came across this post from another comment you left.
There are definitely things that resonate here, particularly letting go of our expectations. This is something that, in recent months, I have been focusing upon in my journey as well, and I think I mentioned in one of my posts when I came to the realization that I truly did not handle negative changes well. I may strive to do my best, but ultimately the outcome may be out of my control. Knowing that I have put in the effort, and that sometimes positive outcome may occur, should be good enough.
Attempting to find peace with my current situation was integral to improving. If I'm not able to deal with my current stress and life, then adding a few nice things or events isn't going to change it dramatically. I have to extract some happiness and joy from what I currently have (albeit, my life is primarily work, transit, and duties right now... only "fun" time is a bit of TV while I eat dinner). Anything additional is simply gravy, and I'll extract additional happiness from that.
Keeping this perspective through tough times is going to be essential. It's already helped me out a bit, but I have to keep training my mind in order to secure this like a foundation to my mental health. There will be more difficult times ahead in life for all of us. Only time will tell how I end up practically handling it.
Hope this little thought will be of value to you as well.
