A lot of these things would've happened even without a lockdown, since if the pandemic goes badly enough, huge swaths of the population would've shut themselves at home to avoid risk of contagion.
Also, the virus is clearly more dangerous than the lockdown: you have seen what happens when the lockdown is applied to the whole population, but you haven't yet seen what happens when the virus has spread to 50%+ of the population (and it's especially ugly if it'd happen all in a short amount of time).
It's sad to know about additional suicides, though the reports I've seen say that there hasn't been any increase in suicides during the lockdowns (but again: it might've been specific to the situation in Europe)
