Anxiety reared its head for me at 31

Before late December 2016, I didn't really experience anxiety that was out of the norm. I had an unusually high heart rate the day if starting a new job. I went in to get checked because heart issues run in my family. Everything checked out so they insisted I was on drugs. I have never done drugs. Things got better quick. Then October 21 rolls around. I get a call at work that my 4 year old daughter had an accident at home and was seriously burned. She spent 3 weeks in the hospital, my wife stayed with her, and i stayed with my son, and newborn. I would make trips back and forth every over day (150 miles one way) to see her and pick up breat milk for the little one. I started getting this heavy weight feeling on my chest, my breathing would change, and I'd get this awful tingle feeling over my entire body.
Once she was home and doing well it subsided some. Three weeks after she came home, my bestfriend and his daughter died in a house fire. I would get these episodes off and on all day, heart rate at times would be well over 150. I went in and was diagnosed and giving some medication that seems to have helped a lot. Earlier this month I lost my Mom, I held her hand as she passed away.. and the episode started, but it only lasted 5 minutes. I haven't really felt much after that, and we where very close.. either the meds and kind of teaching myself to calm down is working OR something is brewing??
Seeing as this came on how it did, can it also "go away"?

I must stay in touch with my own breathing. It is the barometer that I use for determining my well-being and the onset of an anxiety or panic attack.
That numbness and tingling is likely from hyperventilation (too much air) when it feels like you are suffocating (not enough air) and having a stroke or heart attack. This can feed into full-blown panic. I went through this before and now have to constantly monitor my breathing.
I was on an anti-anxiety/antidepressant medication along with therapy for a few years that helped. I didn't even realize that depression was a part of it. I did self-medicate with alcohol, which worked great in the beginning (I had thought), but then it stopped working and actually made the anxiety worse.
I did wear a heart monitor for 24 hours and kept a diary of my activities throughout the heart-rate test. I passed and and the tachycardia has not returned since, AFAIK.
I have cut back on caffeine, sugar and salt/nitrates. No alcohol. 'Situational anxiety' feels unpleasant, but I have learned to deal with it. Just head into it and know that you will survive and come out the other end of it OK. It is one day at a time.
Best of luck to you.

Thank you for the reply. I do not drink normally, maybe once a year or so. Even then it is just some wine with my wife. I had the heart monitor for 3 days, also had ekg etc. Thankfully they all came out good. The first time I had that insane tingling feeling with heavier breathing was terrifying. This kind of stuff is all new to me personally.

If I keep busy, that seems to help a lot. Sitting idle let's my mind wander all over the place.
