Does it sound like I have anxiety?

I was suicidal last year and one day i was severely depressed then I lightly punched myself in the throat. When I punched it, it sent my adams apple (or whatever you call it idk what it really is) back a little bit. It really scared me then I got very dizzy and felt like I was going to pass out. It felt like a panic attack. After I punched it I could talk fine and breathe but I felt like I couldn't. A week afterwards I had a panic attack according to my parents. It was so bad I was pacing the floors and talking very fast. They took me to the hospital and they said my heart rate was very high and they did CAT scans and they took blood tests. They all came back normal then they sent me to another hospital by ambulance and they kept me for a night. They said everything was fine the next day and i got to go home. I went to a heart dr because they think i have tachycardia. They heart dr gave me a ultrasound of my heart and he said it was fine. They diangnosed me with anxiety and gave me medication for it. The medication worked a little bit but the side effects scared me and I still got some panic attacks. A month later I stopped takeing them because I was getting a sour stomach and It scared me. Since then I had a couple panic attacks and they only occur at night. What sets them off is every pain or weird feeling I get and I keep thinking I'm going to die from it. A week ago my mom made me take my medication again without drs permission then I got hot flashes and they scared me so I had a panic attack. Im fighting them back and since I have been feeling very weird. My heart is racing then I start sweating. I have a horrible fear of death and I so scared of dying I'm 15 years old and Im wondering if its all in my head because my parents get agitated by me having panic attacks from nothing and worrying about dying. Its horrible and Im so scared of it. Some people have told me I should go back on my medication but I'm afraid to take them. When I have a cold and I take medicine for it I have a panic attack and my body flushes the medicine out. Anxiety runs in my family and its very embarrassing. I keep thinking Im going to die but my parents and friends assure me I'm not going to. This is so horrible I want it to stop.
