Advice please, first time member, panic attack

I just really need advice because I'm scared. Last Thursday I believe I had a panic attack. Let me add I feel real good in life, I love my job, for the first time in my life I'm financially secured and I'm with a man who I love. So last Thursday I'm watching tv and I feel this weird feeling in my stomach that rises to my head. My heart is raising so fast, I can't breath, I have goosebumps but sweating like crazy. After hours I start to calm down (I was prepared to call 911). So now everyday I feel it's going to happen again and I'm terrified because I truly thought I was dying. I saw my doctor who listened to my heart, checked recent lab work and everything seemed fine and he said i had a panic attack. So since then everyday I've been scared but today I felt this weird feeling in my throat almost like a lump but I could swallow. It travelled down my body and I started to sweat again. I kept breathing heavy and told myself I'm going to be okay. Is this normal for an after affect of a panic attack? I was able to beat this episode and feel okay but I'm scared. I guess I need reassurance that it's normal when someone has a panic attack

Actually, I should be more honest and say I took diazepam after I started to feel another attack coming and told myself I'm not dying it's just an attack...but my fear comes from the feeling I felt that started the episode... Is it normal? Ps, thank you Larry for responding

Sounds like panic attack, when i had my first attack i thought i was going to die. Though you know your condition to be because of panic attacks, i suggest get a complete physical check up as well.
