Honestly, Jessie, I think most people, when they are told their apnea must be treated with CPAP, have concerns and almost a period of mourning that resemble what you are going through right now. The treatment (CPAP), while effective and life-saving, is the proverbial "hard pill to swallow" and doesn't seem to be replaceable any time in the near future. There are a few things to remember... 1) CPAP WILL make a huge difference not only in your sleep apnea, but also in your overall health. Obstructive Sleep Apnea (OSA) is extremely common (though many remain undiagnosed) and is also related to or responsible for a number of very common disorders such as hypertension, diabetes, high cholesterol, heart disease etc etc etc. Every night on CPAP is a CHOICE to do what is best for your mind and body. 2) CPAP is SO MUCH more comfortable now than it used to be... no, it is not an easy therapy to adjust to, but you have so many options in treatment equipment now that you are in a pretty good time to be diagnosed. Masks are feather light, machines incorporate exhalation relief functions to ease your discomfort, and special bed pillows are not designed to all you to sleep on your side and wear any mask. Make sure to advocate for yourself when getting a machine and mask - don't just settle for what the DME has on hand that day - mask comfort makes all the difference in patient compliance! Exercise your right to try a mask and return it for another if it doesn't work (times on these policies vary by mask manufacturer - Respironics has a 30-day mask comfort guarantee on most masks and also a guarantee on their patented C-Flex machines). DMEs are not always the easiest with which to work, but a little extra effort on your part (even though it should be on theirs!) will give you a much better chance of therapy sucess. 3) Oh CPAP and the single gal - why was this never covered on Sex and the City 
! Well I can say this, a little humor and self-confidence about your treatment and it's benefits will go a loooooong way here... if you can educate a potential partner on the dangers on NOT using your CPAP, how could he say anything about it?!? And if he did, would he be the guy to marry?? Call it the "CPAP Test". Hey, in a perfect world, he would be on CPAP, too! Cross your fingers...
Good luck, Jessie - what you are feeling is so common... better to process it now than be in denial about how life-changing CPAP is! But remember, it is also life-changing in a very positive way!
