Heart Attack or Anxiety Attack? HELP ASAP

[Wintear]

About 25 minutes ago, I felt a very uncomfortable sensation in the middle of my chest, almost as if my heart stopped or came close to stopping temporarily. I clutched at my chest and felt my heart start beating really fast and pounding hard. This got me worked up and I began to sweat, shake, experience tingling in my hands/cold and clammy, and feel off/on tightness in my chest. I also got really weak (physically) and it took a bit of effort to move myself from my computer chair to my bed. (I was watching YouTube videos and eating saltines when this took place out of nowhere..)

I'm laying down and I feel slightly better, though I'm still very anxious and tensed up. I'm getting heart palpitations as well. I'm trying my hardest to keep a level head. The pinky and ring finger of my left hand is still tingly.

Is this anxiety/panic?
I'm very scared right now. I just had a blood test, blood pressure/vitals checked a little over a week ago at the doctors. Everything came back normal and clean.

Help? Anybody? :/ I'm convinced I'm going to die.

Oh, and I keep getting a little dizzy off/on, too...

Hi
It sounds like a panic attack,but only your doc could tell you for sure.
I've had very similar symptoms when I've had them.
Its scary if you've never experienced one before,but it will pass,just try and let yourself relax as much as you can,and try not to tense up.
Check your breathing and keep it steady as you can.
You were probably breathing quite shallow while it was happening.
Just wanted you to feel less alone

Thank you! I've suffered with GAD since age 8.
I don't know. I was just sitting there, occupied and bam. It hit me like a truck out of nowhere. It was really scary.

I've been in bed ever since... I feel rather crippled by this.

Hope you're feeling a bit better,and calmer,than earlier.
Take care
