Do your meds help with avoidance??

One of my biggest problems is constant avoidance of tasks due to the anxiety associated with a fear of not doing it well/rarely finishing anything. I'm planning to apply to uni next year, so have started the process of getting referred for meds (I was diagnosed last year). So basically l'm just wondering if meds will help with avoidance or that's a separate anxiety/fear thing I need to work through myself? :)
