About 3 weeks ago I had surgery on my arm after I broke it. After the surgery was done I had moments of moodswings and anxiety. Last night I couldn't get much sleep cause I started having existential anxiety and intrusive thoughts. I felt weird feelings in my heart which also triggered my cardiophobia leading me to believe I would get a heart attack. I think this is all a result of me still dealing with post-surgery anxiety. Can anyone tell me how long it lasts for, just so I know it's not dangerous and my mind can be at ease? Thank you.
