Spiders used to scare me, but, eventually, after seeing so many in games and real life, it came to the point I was able to pick them up while it is alive and gently let it outside. It took awhile though. The only fear I have now are the depths of an ocean where you can't see the bottom. I just started playing Subnautica, though, and it is becoming easier to deal with. Truthfully, you can get over any fear, but you must face it, which will not always be easy. It's OK to fear, but what matters is how you handle it, not the existence. The easiest way to deal with those spiders (in spite of fear) is to use a ranged weapon to clear as much webs as you can. If any crawlers approach smack em back until you hear their weird monkey cry (or whatever it is). Whenever none are attacking, light up the battleground too with torches, in order to ease the slight fear of the spiders coming out from the darkness. Once the whole nest is gone and lit up, it is not as scary any more. If the cobwebs spawn next time you visit, just clear em.
