Well, Of course Life isn't easy. If it was, we wouldn't be tried, tested, and forged in the fire of life. If life was easy, we wouldn't grow better, or learn, we wouldn't change. If life were a series of lovely days, we'd soon get bored. If there was no rain, then there wouldn't be any feeling of joy when it finally stops and we could go out to the beach. If it was all easy, we wouldn't get stronger.
So be thankful it is a struggle sometimes, you're being forged in the fire, and the outcome is usually beautiful.
