Anxiety morning after drinking?

I had a horrible thought and it was my own thought. I feel awful. Also my heart is racing all the time

Can someone help me? I was trying to clean my daughter’s car got hot and got anxiety now all I can focus on is my heart rate and it doesn’t feel good and I am freaking the f out!

I had my first serious anxiety related episode back in April and then once in May. My husband had lost his job due to health reasons and spent six weeks looking for work before he finally found something. It was up to me delivering for spark to make the bills. The stress built up and in May I had a panic attack that put me in the hospital. I started Sertraline, had some rough side effects but still noticed a positive change in the anxiety. I still felt crappy every day, but less and less crappy, if that makes sense. (Nausea, heart palpitations, weak, anxious). The month of June was great, no huge panic moments, no racing heart, etc. In one day I went out of town by myself, drove on the interstate, (that’s always scared me), went to the dentist and took my son out to lunch and dined in. It was great. The next day, I argued with my teen all day, it exhausted me and I was dreading spending an hour that evening talking to my therapist. I was just too tired, you know? About twenty minutes before the appointment my anxiety ramped up. Racing heart, trembling, feelings of dread. Normally I can get it under control with breathing techniques but I didn’t have time to before my appointment. Luckily my therapist had overbooked and called me to cancel, so I just rested for the rest of the night, but that’s been six days ago and I’ve struggled ever since. The day after that I was weak and shaky and could feel my heart beat, the day after that I was tired and really beating myself up for what felt like a failure to me, and the last couple days it’s been on and off heart palpitations (my heart rate isn’t going up high, I’m just super aware of my heart beat) and it’s very uncomfortable. My family keeps telling me it’s because I’m stuck in my head and I know that’s true because I spent hours outside in the heat doing garden work yesterday and instead of feeling even worse I felt amazing for the rest of the night and I’ve felt pretty good for most of today. So I know in my head that anxiety recovery isn’t linear and that anxiety hangovers are a real thing and that i just have to be patient for a few days after an attack, but sometimes it’s so hard to think like that when I’m in the middle of feeling so crappy and shaky and weak. Does anyone else feel discouraged like this sometimes? Is what I just described similar to anything anyone else has experienced? If so, what were some coping techniques you used?
