I have adhd and I dont know what to do with myself?

I recently found out I have a very serious case of adhd. I'm a 13 year old girl. My mom dosen't pay much attention to it, though I struggle with every day functions. How can I make my mood swings, impulsivity, lack of concentration, and "weirdness" go away? I don't know how to live a normal life and I'm sick of it. I've tried everything. help?
