You’re anxiety might be playing into your need to succeed. If it’s failure you are afraid, you really need to learn to become more comfortable in your skin. Don’t readily accept new opportunities, instead let them hang in the air for a bit(a few seconds at best). Let yourself be confronted with anxiousness until it is fully acknowledged, then accept it and make your decision.
Start prioritizing other things once you are more comfortable doing so. Have any hobbies?
