I'm not in any way qualified to give professional advice, but I do have a good deal of experience with making people feel better, so I'll give it a shot.
Breast cancer has the highest survival rate of the spectrum. If your mom has a lump in her collarbone, it's probably a bruise, and almost definitely not related. Same wiht the urinary problems, there are a multitude of things thta can cause that, and all but one of those things are
not cancer. The first sign of a spreading breast tumor is that it attaches itself to the chest muscle wall or spreads to the underarm lymph nodes. The doctors would surely have noticed either of these by now, and if they didn't tell her about it, you can be almost positive that it hasn't happened. If the tumor hasn't spread to lymph nodes, and hasn't attached to the chest muscle, it's most likely still in stage 0 or stage 1, which 100% and 98% survival rates.
It's prefectly normal for your mother and your family to be worried, as it is in any situation where a family member has a chronic illness. That's really what cancer has become these days, a chronic illness,
not a terminal illness. Just last week, a new drug was announced that was shown to stop or shrink tumors in over a third of breast cancer patients who had previously been given less than 3 weeks to live. If a new medicine can do such wonderful things for people who had no hope, I'd say that your mother will be fine with nearly a 100% chance.
So, you also dented a fender. This really isn't the end of the world. A matching panel from a junkyard shouldn't cost more than a hundred dollars to replace. In fact, if you ask in the motors forum here, people will be more than happy to point you to the cheapest places they know of to get replacement parts.
Next, your boyfriend is on vacation. He's only gone for a few more days, and you can be sure that he wouldn't want anything more than for you to be there with him. Just think of how happy he'll be to see you when he gets back in a few days. Close your eyes and imagine him stepping through the door and giving you a big, warm bear hug and not letting go until the two of you can't stand up.
Last, there's the fear of driving. You've probably been driving for a couple of years, and the worst you've done is dent a fender getting gas. Nobody got hurt, maybe you were a bit embarassed, and it wouldn't have seemed like such a big deal if you didn't already have so much on your mind. Everyone bumps a light pole, or a railing, or even another car at least once in their life. You've probably driven that same route for almost a year now if you're at the same school. You could probably drive it with your eyes closed. If you wear your seatbelt, you can survive just about anything. Put on some relaxing music, take a deep breath, and reassure yourself that the only way to conquer your phobia is to confront it. Every time you get out of the car after driving, you prove to yourself that you don't have to be afraid.
