Can you help me get my epi pens, other meds--and a safer tooth extraction?

On Christmas night 2014 I woke up with my tongue swelling up so big it completely filled the inside of my mouth starting to cut off of my airway.

My daughter called 911. I was having a life threatening allergic reaction to a pain medicine. The ambulance drove me to the hospital where I finally got an epi shot. Needless to say, the incident was very scary and haunts me to this day. I have to get my own epi pens to always have near me so they can save my life if it happens again.
But they are very very expensive-even with my insurance,

So I am asking everyone for help. My family's resources and not there and I have no money or savings.

I have chronic multiple sclerosis and numerous ailments that consume my small resources and I have not been able to buy the epi pens, other necessary medications orgroceries at times,.  

The other worrisome thing is that I can no longer take any narcotics forpain. I just found out one molar has to extracted---but without any pain meds!! My tooth extraction is also worrying me due to any hidden other allergies I might have.
