Feelings of negativity and fear.

In the last year I have had an experience of panic attack and till date I have had 4-5 panic attacks. The experience has been very fearful and I consulted a lot of psychiatrist who advised me some medication and breathing exercises. I took the medication but I did not feel good after taking since I felt I was not in control and experienced loss of appetite because of it. I started breathing exercises and it has helped but sometimes the fear gets overwhelming a lot. I want to overcome this fear of panic attack and because of this fear I feel I may die and it's very challenging to get my thought process right. Last year was very stressful on my mind and body and I guess because of this I started having panic attacks. How can I overcome this fear without medication and never get such a bad feeling.
