The answer to your question may lie in the question. You’ve used the word “obsessing” and I would wonder what that implies exactly. If you continually berate yourself or are embroiled in an internal debate that involves intrusive thoughts, the issue may not be so much about wrestling with an important decision as it may be about your state of anxiety and mental wellness. If your “obsession” is causing you to lose sleep, withdraw from loved ones, feel indifferent about eating, become tardy, or become so distracted that your productivity decreases, you should seek professional support for what may be anxiety, depression or obsessive-compulsive disorder.
If obsessing about making the right decision is more about second-guessing your choice(s), you may benefit from spiritual counseling. You may be grappling with weak or low self-esteem which may cause you to feel uncomfortable or incapable of doing the right thing. Spiritual or religious counseling may support you to begin trusting yourself and feeling more confident in the decisions you are making, especially if you feel as if you’re not making them alone but in partnership with a higher authority.
Worrying about doing the right thing reflects your sensitivity and caring. But please know that making the “right” decision is entirely a matter of perception and individual interpretation.
