As someone who had friends locked up in mental institutions and spend a few weeks in a hospital psych ward DO NOT DO THAT.
They will not help and in most cases it makes everything worse. the only thing they do is drug you into a semi-coma and beat you whenever you don't comply with their bullshit rules and behavioural guidelines.
getting admitted into a psych ward is already a death sentence, being commited into a psych wars as an INCEL is 1000x times worse. they will take all of your money away and lock you up for the rest of your life since no one will come looking for you.
you will be abused and treated as a punching bag for the guards and "doctors", I know we are already the punching bags of society and the life of an incel is harder that the life of any minority, but it gets worse.
I don't know how you feel, but do not go into a psych ward.
