overcoming a fear

in all honesty, i am afraid of a lot of things but I have just overcome one of my biggest fears. my biggest fear would be spiders. my dad has recently started a hobby where he collects tarantulas and having them in the house makes me really anxious. but last week my dad was holding on of them and I was skeptical at first but then he let me hold it and I didn’t react like I thought I would and it wasn’t as bad as I expected.
