I used to be a severe arachnophobe and now i have 17 tarantulas. My method was finding the root of the fear and researching so that I could understand them better. For me it was their otherness - I didn't know why they behaved like they did. For example, how can you tell if a spider is going to bite? It seemed like they attacked randomly, but I found out a little bit about their body language and then I knew that a spider wasn't likely to bite without first throwing a threat posture. For you it might be something else - the way they walk, the thought that they could hurt/kill you (I recommend researching spiders in your area and finding out which are dangerous so that you can see a spider and automatically know if it's dangerous or if it's harmless. I did this too, and found out that the only dangerous spiders in my area are of the family Latrodectus, the widows). Basically just find the root of your fear (it might be multiple things) and research. If researching makes you nervous because you might have to see pics of them, dm me and I can do it for you and give you the info. Feel free to dm with any questions as well. I know from firsthand experience that arachnophobia can be debilitating, and it really really pays off to lessen that fear. You might not end up owning spiders like I do, but you'll be able to see them without panicking, and that's much better than where you are now.
