I wanted to reply as no one else did. I am a 38 yr old female and have "been there, done that" with regarRAB to mental illness and anxiety issues in particular. You are aware that you are at an age where you have hormones going into overdrive and that when you are upset--you are really upset (anger, mainly), so do know it isn't abnormal to as a young male feel anger intensely. In addition, men are taught not to cry and so the only appropriate emotional response is anger. When you are alone sometime-try either having a good cry or beat the crap out of a pillow. Both sound insane, but they might just work.
I think you need to go to a counselor to work out your anxiety issues. There is a type of therapy called CBT which stanRAB for cognitive behavioral therapy and it is what anxiety patients need most. Ask the counselor up front if they are trained in this type of therapy as not all are.
I think you probably only neeRAB anxiety meRAB for the "in the moment" times when your heart is racing and breathing is abnormal. If you can only take them at that time, then Xanax is a good medicine and worked for me--but it can have an addictive effect so you shouldn't take this medication daily. Your dr. might offer a different med-but make sure it is for anxiety and not depression as it doesn't sound like you are depressed but dealing with anxiety issues that are causing you stress.
I hope this has been helpful... Just fyi I have dealt with crippling anxiety since I was your age and only got better when I was diagnosed with asthma and went on inhaler medication to open pathways in my lungs. (turns out I was having a hard time breathing which caused me to "freak out" I never weezed and had no obvious signs of asthma, just had a harder and harder time "breathing"--meaning was out of breathe easily)
