Can you outgrow being squeamish?

I’m going to vet school in September and it’s my absolute dream to be a vet and I worked so hard to get in and to be in the position however I can be slightly squeamish around veins and blood and it’s worrying me. I’ve done weeks of work experience in vet practices before and I usually become much better towards the end of the week having been exposed to it all and don’t get me wrong I can deal with a blood, injections and surgery ect however occasionally when I see something extremely gruesome in vet practices I have felt a bit sick. I guess my question is did any other vets/vet students feel this way when they first started out and did you get used to it the longer you were exposed to it? Any advice or help would be very appreciated thank you!
