Certainly is not.
Youve come this far, so news like this is just another thing you need to figure out how to climb over and make sure you put a boot heel in its face when you do.
As has been previously stated, there are a lot of options when dealing with this.
Go in with a positive attitude and an open mind, but a realistic perspective.
Theres no magic pill.
There are a lot of good, tested and vetted methods to beat this.
Most of them are going to take the lead out of that pencil

, but will let you keep living and doing everything else you want to.
There are also options for getting that pencil to write again,

so that shouldnt be a deciding factor.
Youre only 25 once, just sayin.
