My phobia of roaches controls my life

I have a severe phobia of roaches and it consumes my life. I think about them like 50 or more times a day. I remember every single place I've ever been where I saw a roach and I will never go in that spot again. I'm so terrified. People think it's funny but honestly, I know if one were to touch me, I would die of heart failure. I have stress induced asthma and whenever I see a roach, I hyperventilate and have an asthma attack and then I cry for like an entire day. I literally shut down when I see them. I don't know what to do because no one takes me seriously. I'm also terrified of the movie "The Goonies." I have a phobia of the guy on there who is all messed up looking. :(
