Of course, it can. It's not always easy to put thoughts on the page (thus the term "writer's block").
However, once you're there and in the habit of writing, it becomes easier... and easier to form the sentences that take shape... and easier to have new ideas... and easier to see with a bit more clarity... and connect and share.
So take a deep breath and relax into the hard work. As you grow to enjoy it, it will become less of a job and more of a passion - something that you'll do without even thinking about it because it will just come naturally to you.
Perhaps another way to say "relax into the hard work" is to enjoy the process. Don't wait for the outcome to feel good. Soak in how it feels to be in the moment.
How about you? Does writing feel like a chore?
