This is my first write.time writing here, I'm very excited. I hope everything will be okay for me.

When you wrote, 'first write', it didn't make sense. I changed it to 'first time' as this is your first post on this site, and I added ' writing here', meaning writing on this website. You spelled 'excited' as 'exited', which means you left, but that's a super common mistake!

I am biologist. I love my job but now I'm working aboutwith insects, and it's a little bit hard for me because ıI am afraid of insects.

Wow, a biologist! I wrote working 'with' insects as I am assuming you are studying insects right now. I added an apostrophe sign in 'its' to become 'it's', because it is a contraction of the word 'it is'. The letter 'i' in 'is' is removed and an apostrophe takes it's place. I added that you are afraid 'of' insects, with 'of' being a preposition, which relates that insects are the thing you are afraid of in your sentence.
