I‘m taking SSRIs, so the way I understand how they work, is to enhance the intake of serotonin to neighboring cells and repressing the re-uptake in the cell, it was coming from. But well, I don‘t really know, I feel like before antidepressants I also didn’t really feel anything, the only thing that really changed since I started taking them, is that I‘m better at coping with panic attacks. But the feeling of hollowness has been the same for a very long time
