Having grown up with a father who battled with issues of the mind for decades, I certainly feel symphatetic towards anyone battling with themselves. But remember that you yourself have the most responsibility and face the biggest risks when it comes to faults of the mind.
If you feel bad for days or weeks on end, have trouble sleeping, notice sensory illusions, seek professional help. If the mind collapses badly enough, society can take all your personal liberties and responsibilities, and relegate you to a status where you dont even control your own money. Worst case scenario: Mental asylum for an undetermined amount of time (from weeks to several decades). If you stay in long enogh, the person coming out at the end of it will not be the same person it once was.
I say this not to guilt or scare anyone, I truly wish everyone well battling with these things. I just want to emphasize that these things can be dead serious matters and just getting wasted and reading self-help will not be enough. Take control of your situatuon, if you need help to do it, get help. Dont feel any shame in doing so either.
However, even if doctors, nurses, counsellirs and pills are there to help, they can only do so much. Having family and people close to you, who do not judge is paramount and their goodwill and love towards you is an asset you can rely on when you need energy to get by.
Everybody has their ups and downs, even “sane” people. Remember It can’t rain all the time, even the darkest moments will pass and make way for better. And when you get there, you might feel stronger having to come out of it all.
