Hi and welcome! No need to feel stupid. If it's any consolation, I'm coming to the end of my second year of my BSc in Psychology with Counselling and I have a level 1 in Counselling too. I have no idea why I'm depressed or have anxiety, I just know the meds I'm on control it. Besides, if your BSc was anything like the psychology aspect of mine, it doesn't really focus on mental health, but general psychological theories
