Anxiety is back?!

Anxiety is back?

I have been diagnosed with anxiety in the past. Went to the ER with chest pains, racing heart, and they did several tests, chest X-Ray, etc. Followed up with my doctor, who sent me for a stress test and a heart ultrasound. Everything came out normal.
My doctor prescribed Zoloft, which really helped, and I took it for 6 monts, then quit it on my own, because I was not okay with staying on them.
Anyways, since I was like 15, I've had "cycles" of anxiety. Like I'll have anxiety and panic attacks often for a few months, then weeks will go by where I'm fine.
Can anyone relate?
I have had bad anxiety for the past couple of weeks. Weird pains, racing heart, sweaty palms, extremely tired, afraid of fainting, fidgety....If anyone has natural ways of dealing with this, please let me know.

I stopped taking the Zoloft cold turkey, but this was over 2 years ago.

I was having anxiety attacks a couple of years ago while having some health issues. My doctor told me to "talk" myself out of them. He said I was an intelligent person and that although it seemed as if I would die (racing heart, feeling like I was going to faint, nausea) I obviously wouldn't, because I was healthy. The next time I felt one coming on, I just repeated everything to myself that the doctor said and it stopped. I did that a couple of times and then they stopped completely. I hope this helps.
