What may be happening
Requests may trigger immediate anxiety about being seen as selfish or mean. You might say yes automatically and regret it afterward.
What can help
Start with small nos in low-stakes situations and notice most people accept them. Use brief, kind scripts: "I can't take that on right now." Separate guilt from facts—declining is not the same as rejecting the person. Examine childhood messages about whose needs mattered most. Track resentment as a signal you have over-yes'd. Practice tolerating others' disappointment without reversing your boundary.
When to get support
Consider professional support if symptoms persistently interfere with daily life, relationships, or safety. Seek urgent help if you are having thoughts of self-harm or feel unable to stay safe; in the U. S. , call or text 988. Seek therapy if inability to say no drives burnout, one-sided relationships, or chronic resentment.
