Q: Power steering

Noticed a whining 2 weeks ago. My dad looked and saw my power steering reservoir needed more fluid. Thought it was an easy fix but. Within the next week it was making the same noise along with a burning smell. We filled the reservoir again and called my mechanic. He couldn’t fit me in until the best week so I tried my best to not use my car but I needed to get around. He replaced a hose and I got it back yesterday but now it’s the next night the steering wheel was very tight and made a loud groaning noise every time I moved the wheel at all, no matter how little I turned it. The fluid was already completely gone so I added more and drove it down my street to let it get into the system. But as I pulled out of my driveway it had already dripped in the driveway. And I’m 100% positive that nothing spilled when I was pouring it.
