<human>: I'm thinking of buying tickets to see the Deftones this March in Texas. I want to attend along with my two best friends. I have the money and a ride back and forth to the venue but the problem is.... I have terrible social anxiety.

I'm not a good looking female nor am I skinny. I'm afraid of the looks I will get and the millions of scenarios that could happen.
What if I freak out and have an anxiety attack in the middle of the venue? What if my phone gets stolen? Date rape drugs? 

I haven't been to a show or a concert since Disturbed and korn performed here. My friends had to drag me out of my bed and I did have a good time but I was scared as hell over everything. I had to smoke several bowls of the green in order to mellow out.

But I've since quit smoking and drinking, due to attending college and school is my most important priority.

What can I do to convince myself to attend the concert of one of my fave bands of all time and relax? How do I prepare myself to have a safe and fun concert experience? Or should I not attend at all and save my money?

Can you summarize the given text in a few sentences?
<bot>: too scared and anxious to attend Deftones concert. Even considering not attending at all. Need advice on having a safe and fun concert experience.*
