So anxious

Last night I ended up having to leave work and go to ER. I woke up for work and started feeling like I couldn’t breathe deeply or catch my breathe. My heart started racing and I got so worked up I threw up. I still pushed and went to work. A couple hours in I started pouring sweat and almost passed out. I was finally able to leave and get checked out. ER found nothing besides I am dehydrated (not surprising since I throw up daily). I honestly think it’s anxiety. Today I am 13 weeks and 1 day, I was exactly this far along in January when I miscarried our son. I think this day is getting to me more than I’d like to admit. I am normally not an anxious person at all, so I’m kind of stumped. I am feeling a little better this morning but the heart racing is still coming and going. I plan on talking to my doctor about this at my appointment in a week but I am not really into medications. What do you guys do to help ease anxiety? I am so desperate.
