There is no drug without possible side effects. It all depends on the administration route, dose, and most importantly; your tolerance. Spironolactone is an anti-androgen, which means that if may affect your brain. Depression is a common side effect of androgen deprivation. Anxiety may be linked as well. However, a lot of things may cause these psychological issues, so if you don't want to pause treatment, you'll have to rule out everything else. If you can't do it, I'm sorry, but the only way to be completely sure is to stop treatment. Give it a week. All side effects should wear off, and it won't damage your hair.
