It’s treating the symptons, not the cause.
the idea is that treating the symptoms can give you the energy and drive to address the cause(s). It’s not an either/or situation.
there are other anti-depressants around and you can find comparison tables on t’internet explaining how long they take to kick in, likely side-effects etc. There are differences even between drugs in the same class.
I totally agree with the suggestion that depression is a consequence of MTFU too many times before
