Definitely needs a lot of work before that story will be good. Even if it's a "comedy mod", nobody will be able to understand what's going on if you're playing the mod and everything happens like you explained it.
For instance, why did you hide in a cabinet? That makes absolutely no sense, unless you had some kind of previous knowledge of this operation happening, and then you would just get out of the school as fast as possible, not hide.
The secret room and the "anti-bully suit" just seem to be convenient ways of getting an HEV suit replacement on the player. I'd completely eliminate this part, and just give the player a HUD to begin with.
Having the Black Ops just "suddenly come in" is also pretty lame. It doesn't need to be anything fancy, and it could be for some humorous reason, but you need SOME reason why they "suddenly came in".
And last but not least, stop using "ur" and "u". It makes you look like an incompetent n00b, and people will generally take one look at a description written like that and decide you aren't serious about any of it.
