I feel like I'm suffocating. Is this anxiety?

I'm about 23 years old. I have been having belly button pains that come and go mostly due to anxiety and whenever I worry if the stomach pain might kill me one day, my panic attacks happen and I feel a tightness in my chest like I'm suffocating, and I start gasping for air. This has been such a hard challenge for me to get through and I worry about my health every single day. The pain is discomforting. I'm not sure how I can calm myself down. Should I be concerned that my life could be at a end? I had this feeling for weeks now. I don't feel nauseous or anything, just dealing with belly pains and discomfort in just one spot.
