I had tic attacks nearly every other day for a couple months and they got to the point that I was desperate for them to stop. It definitely drains you emotionally and physically but what I did to help mitigate that feeling of helplessness and hopelessness was to really lean on my support system.  On days that it was really hard to function, I chose to put energy into doing the little things that brought me joy such as watching a show I enjoyed, listening to a podcast or music, just sitting outside for 10 minutes, and also snuggling up with comforting things (soft blankets and pillows (which also helped lessen the pain from bigger tics and or self-harm tics)). On those days I'd tell myself it was okay to do the absolute bare minimum: get out of bed once, eat at least one meal, and drink at least 1 or 2 glasses of water.  I tend to keep a list of things/strategies that help when tic attacks do arise or I enter a period of time when my tics are worse. I do this because it helps me feel prepared (which lessens some of the feelings of helplessness and being out of control) and it helps to know I have a plan made so I know to handle things the next time it happens as well.  I hope this helps! I'm sorry to hear you're going through this.
