USPS losing mail under my name

I live with roommates, usually I receive mail once a week or something, I noticed the last month or so I haven't received any mail, but my roommates do receive mail regularly, anyway, I was waiting for my driver's license from the DMV, it appeared in the USPS Informed delivery thing on Monday, and I haven't received it since then, I am so frustrated, Also my insurance company mailed me some sort of notice last month, that I never received.

What am I supposed to do, If only mail under my name is being lost?
