How are you doing? Was thinking of you tonight. Did you talk to your doctor about the medications? One thought I had...and I could be way off base here...do you think it's possible that the increased heartrate and choking sensation you experienced could have been anxiety? I know you were anxious about trying the medications...anxiety often goes hand in hand with depression...and those symptoms sound a lot like an anxiety attack. My difficult child has severe anxiety and panic disorder and she will experience shortness of breath, racing heart, and feeling like her throat is swelling. Just a thought I had. Hope you're taking care of yourself.
