Thank you for sharing, Ousaima!
So it's your identity to take other people's pain. It energizes you, but only for as long as you're needed. When you're not successful, or when someone "steals" the reward, your scale flips. Anyway, you overpower your body, it's a catch-22.
But have you ever learned that you ARE a wonderful and valuable human being, you cannot be other than perfect, no matter what you DO and what the result is? Because the immediate result depends on others' readiness, and the later result we can't perceive from where we stand. 
Your happiness and energy could be completely independent from these immediate results and from other human beings. It's a matter of expanding your identity. Is there anybody in your life who or what can teach you that and who you believe?
