Concussion

Well today at soccer I bumped my head hard on another kids head but I got the worst of it. I have a huge bump like half dollar sized on the edge of my forehead and I feel really tired and easily frustrated. Could I have a concussion? My mom is paranoid...

and thinks so but I'm not sure

 
It's possible but not probable if you weren't knocked out.

Being really tired may be the aftereffect of a super adrenaline rush you may have had after the accident. The frustration may be a result of your mind and body being confused by the events of the day.

That all being said, if you develop persistent headaches, dizziness or vision problems over the next 24 hours, then you might want to be checked out by your local doctor.

 
Friendship is continuous!

Those whom I meet, as Friends I greet,
And as a Friend I treat them so;
That when in need, or sadly grieved,
I may help their Spirits grow.

So when I hear, upon my ear,
The sounds of troubled Souls;
I can do no less, then to do my best,
To help them toward their goals.

And I know I'll find, with the passage of time,
That I've helped their Spirits grow some;
And though appreciated, thanks aren't awaited,
For my friends are always welcome.
