My intentions are always misunderstood. Am I just being anxious? Or is something wrong with me mentally?
Not sure. What intentions are being misunderstood, or how you communicate your intentions. There may be a communication problem. Why not make an appointment with a therapist to help you communicate your intentions.
Diffrent reasons. There might be the way you express yourself/understand your own inner motives or cues which are misinterpreted by others or miscommunication by you. Anxiety is one of the many reasons why this is happening. Much more information is needed to explore more accurately.
