| “Lately, I've been feeling really low. I can't make myself leave the bed; I start crying out of the blue, and everything is so heavy. I've always suffered from depression, but I've never been to therapy because I couldn't afford it on my own, and my family didn't ever suspect anything. Yesterday I discovered that my university provides psychological help for students for free [...]. On the other hand, I have nothing to lose because it's free. Did you ever try anything like that? Should I use the psychological help service that my university provides for free?” |
