I understand too well, how photographers with a favorite camera or lens can be aggrieved when it acquires a scratch or a dent even when its a minor scratch or dent and inconsequential in terms of performance. I have been through it many times myself.
In your case I can assure you of two things. Your upset will fade over time and continued use of the lens which will desensitize you to its injury. A front element scratch as you describe it (dust size) will have effectively zero impact on images. That is the good news. The bad news is that if you cannot wait until you do get over it, there is no way to "fix" a scratch as such, though, as at least 1 other poster says you can use a black marker to fill it and stop reflections - if you can see them in images. Which I doubt in your case.
When this stuff happens to me these days I try to remind myself of a BUddhist saying that everything dies, everything becomes broken. The way to happiness is to accept this reality and consider it as already broken or damaged even before that happens. That way, if it eventually does happen, you will be less aggrieved - and if it does not you are ahead of the game. It kinda works by stopping this stuff from messing with your head.
