Tics in a day

There is one week left until I get my results. The A-level grades have been downgraded and many haven't got into their uni places. This is just really evil. I really hope that my grades and the rest of my years haven't been downgraded because I think I will cry. 

Today was a good day though, I went out with one of my best friends and had a really good time. I try not to supress my tics but I can't help it. I don't stop my mouth but I always stop my other tics. I cough but I don't make any of my other noises because they embarass me. I don't want my friends to see the worse tics. I'm scared to show them how bad my tics are, especially my animal noises ones. 

I want to not supress them. But I don't know how to stop. Every time I go out, I try to not supress. I'm really struggling and I don't really know what to do.
