Damn dude, that's just a tiny bit harsh. Why don't you tell me how you really feel? Also, why would my mom go back in time to get cancer? That makes no sense to me. If you were hoping her getting cancer would prevent my birth that wouldn't work. You can thank advances in medicine for that. And finally, I'm glad I only "seem" that way but that's a matter of perspective and opinion, yours of which I don't care much for at this point.
tl;dr: Pop a pill to lower your blood pressure, stfu and chillax dude.
Nemesis is always like that, don't mind him.
Well, I guess that makes more sense but I still don't get why she (herself) would purposely go back in time to get cancer. Is she using a DeLorean or the machine from The Time Machine? Here are two pics just in case you need visuals:
Doc Brown's DeLorean:

Alexander Hartdegen's Time Machine:

Also, how far back in time would she go? Is she going to start a chain smoking habit of some kind? I feel sorry for you, though. It sounds like you've had a rough childhood especially with the way you lash out at people you don't know online. If you need a friend, I'll be your friend.
Thanks for the clarification, by the way.
