wow its like you posted my experience w/ pcs. i also am returning to school in sept. i did 2 courses this summer but they were both online lectures so i didn't have to physically attend classes. in sept i'll actually have to be in class and i'm worried. my main symptoms are cognitive and physical fatigue. i'm afraid my body's gonna shut down @ some point. it sucks because this is my last year, the year that you absolutely need a good GPA ;(
