Just need to vent

I found a rather large lump on my left breast almost a week ago and have another week before I can get in with my obgyn. I have been beyond stressed to say the least. When I was 16 I had a lump removed and it was benign, but this one is so much larger and kind of goes into my armpit. Of course Dr. Google has just made me stress even more, and the wait it getting to be unbearable. I also have this guilt because I knew I had another lump but it was just hanging out not really doing anything and then boom it grew and my left breast which has always been smaller is now much larger. All I can think about is my breasts. I know that whatever this is is going to have to be surgically removed as it's basically my whole breast now and of course I'm stressing about that. What did everyone do with their time? Is their a way to get the process going a little faster? I can't imagine being referred somewhere and having to wait another two weeks to be seen by someone else. Of it is breast cancer how aggressive should I be to have testing done? I have read that because I have had lumps before it could put me at a higher risk of having breast cancer because it means your breast are denser. I really just needed to say all of this somewhere hopefully things will get easier next week when I hopefully have some answers.
