Sarah,
Good Morning. Give yourself a break on freaking out on seeing a spider as you are in good company of many people that have phobias re spiders.
Bats are my downfall. If I even see one hiding in a rafter I will run outside. Others have fears of snakes, mice etc.
Simple, specific phobias are the easiest of conditions to cure.
Though the fear of spiders can be incapacitating for you, both traditional and experimental forms of treatment have proven effective. By slowly learning to relax, manage your irrational fears and cope with the presence of spiders, arachnophobes are learning to live their lives free from the terror. I would kindly suggest you see a therapist to help you learn the best way for you to overcome this phobia.
Kindly,
Kitt
