a phobia to FROGS

I have got a phobia to frogs since i was 16 (i am now 27 years old). I accidentally killed a frog tragically during biology class. I dont think the frog was properly sedated with the other frogs. I wont go into details about the accident but I have been having a hard time with frogs ever since. I cant even look at a picture of a frog without fainting. I had an car accident once as I was driving because a frog crossed the street in front of me. I wish I could be freed from this phobia as I really love the nature. I would love to enjoy hiking and camping without any worries :(
