How can you make new carpet softer?

My parents have just bought new carpet and are going to install it in a couple days. Problem is, it feels absolutely disgusting under your feet. The color is nice, it is greenish brown and fits the room. It is a frieze carpet I think, so if you dropped an earring in it or something you would never see it again and it would get lost in between the parts of the carpet that stick up. My mom hates the feel too but her and my dad spent $450 and bought it off craigslist, so they can't return it. I suggested reselling it on craigslist, but my dad it too attached to the look and does not want to. At this point, I will be wearing shoes 24/7 in my house. I am really angry about this. Also, it is impossible to wheel a wheelchair on it because of the thickness, and I am having surgery in a couple months and need to be able to get around. Is there a way to make it softer? Also, is there any way to make it flatter? I will be totally screwed when I have my surgery because my parents will be at work and I can't walk or maneuver a wheelchair.
