It looks like he is having panic attacks.Better you consult a psychiatrist.

Ok He needs therapy and anxiety management Consult with me or any psychologist for therapy and counseling online or in person

With the description you provided it appears that he had severe panic attack. If it occurs again than he should take medication in order to control the symptoms. For time being I would suggest deep breathing exercises. He should be normal within few days. As he know how the symptom started, next time he can take alprazolam or Clonazepam  .5 mg as soon as he know that symptom is starting, but that requires prescription. If it occurs now and then, than regular medication is needed, and psychiatrists need to be consulted.

Solution is as a start try not to let him alone, next step could be talking to him about his thought after which he gets into such state.

If this problem is old then need to consult a psychologist immediately. He must have some issue bcoz of which he is over thinking. Let him feel important n let him do what he wants to do

Hello, looks like your husband is having panic attacks. He needs treatment for the same. Do consult a psychiatrist at the earliest

You need to be very supportive at this moment and try to find out what is bothering him when he sits alone. Stress, Unresolved negative past experiences, traumas & negative thoughts can trigger anxiety and such situations.

These symptoms are suggestive of panic attack.Yes, anxiety can be reduced with social support but cannot be totally eliminated.
