And don't be afraid of medication!!!!
Medication is probably the last thing anyone should be on, unless a severe hormone imbalance is observed. The way medication for suicidal tendencies works is that it surpresses certain moods. Especially in younger people it has the tendency to also surpress the fear of suicide or any other such feelings that may prevent you from going through with it. By far too many recipes are written out for the sake of convenience but with adverse effects, or simply turning people into zombies.
The human psyche is far more than simply an interplay of hormones. And is not as easily fixed. Deep rooted issues can only be effectively resolved, or otherwise made easier to live with through guidance and talking. Pro-actively trying to not block, but instead cope with certain thoughts.
We need to realize that mental health issues are real and not a fukin joke( yes depression too).
Regrettably psychology is still a developing field that only came around recently since like the 70s. Very little is known at this point, probably no more than 30%, and that's a high estimate.
Unfortunately the usual consensus is to look for long-term fixes, rather than short-term fixes. As such there is no immediate reward (solution) and finding a way to cope with certain feelings simply doesn't appear reasonable. Getting through day-by-day, week-by-week as such should take preference. As often no long-term fixes exist, though there are exceptions.
As someone else pointed out already, it's often difficult to convince someone of alternatives when they're entrenched with their own convictions. But talking does help, even if hearing someone elses' opinion/alternative may not seem feasible. Being pro-active and voicing your thoughts is more than just therapeutic but also liberating as you find out you're not alone, nor does your condition need to remain obstructive for-ever.
I regret to hear of Plato's passing, though I have no immediate connection to him, so I won't feign any real sentiment.
