After being beaten up multiple times I devised a way to lessen them: when they started I would tap my tongue rhythmically against the back of my teeth in a clockwise pattern. This satisfied the compulsion to perform the other tics, at least somewhat. Enough to stop me getting knocked down by other kids.
What I did not ever do, at any point, was use this as an excuse for any failure of any kind. It was my problem and I dealt with it and I moved on to the next 10,000 problems.
I figured out how to get on with my life. Sounds like what you have done is medicalized your problem and used it as an excuse for your failures. I could not care less whether you love or hate me and I will forget this conversation even happened in a day or two. But I will tell you now as a statement of fact that your life will be better if you solve your problems instead of finding excuses for living with them. Weakness is detestable and it brings with it only misery.
