It is possible, get help ASAP. Having to fight a battle with yourself in your head is one hell of a bad experience. It can literally drive you insane from within out. Get help, mingle with friends. Avoid staying alone. Stay away from people you don’t feel comfortable around. Be happy, Live Life. You deserve better. First of all, the level of top 5 (or top 8, or top 10 depending on specific year and set of players) is very close. So, anybody can beat anybody on any given day. Yes, #1 vs #10 would be probably 10:2 if they play 12-matches tournament, still this is is very close situation.
When I was <30, I could go and play tennis for 2 hours on a certain day, sleep overnight and go playing again and again for a week or two without breaks. And I did not control my energy. I threw all my energy without thinking and was fresh next day. I could play for 4 hours too, but I needed couple of days for recovery. Same is now when I am 50+ I still can play for 4 hours and would need couple days of recovery, but I cannot play 2 hours daily anymore. So, the 30+ year old guys do not have the energy that young guys have and they have slower recovery time. But they have experience. What is experience, than?
