anxiety

So I have really bad anxiety, and it has been really bad lately. However I had one durning the middle of school and my friends couldn't help me and I was having the hardest time and sometimes counting down backwards from a hundred works but it didn't I also tried the thingy where you name five things you can see, four things you can touch, three things you can hear, and two things you can smell. However that didn't work at all... I really need some help trying to control it, do y'all have anything that helps with your anxiety????
