good grief no - leave him to his medication. he is not your repsonsibility.
yes i ahve got one of those exPs...
i know how hard it is but you have to completely detach and accept that he is an adult making his own decisions.
given he has been treated he has his own GP and medical profressionals.
it is no longer your job.
your job is you and your DC and helping them thru this.
the only people you shoudl be tlaking to about his meds is to relay info to his GP/medical team - then leave them to deal with it.
keep hi out of your home and as was suggested block his number from dd phone.
it wont be your responsibility if he does kill himself.
keep telling your dc he is ill but he can get help from medical people - not from you. that you, DD, DC cannot fix broken legs and you cant fix someone's head either. but their dad is an adult and he has to be the one seeking help. it is nothing you or they did.
any threats text messages etc - you call police (find out teh local non emrgency number to call) and pass on the details. that is all. dont go tor escue him or invite him into your home.
police will go check him out.
(i did this a few times, funny; each time they called me later to tell me that he had told them he was fine when they turned up....)
say nothing to him other than broken record technique:
you are not my repsonsibility.
I will not be involved with your medication.
you are not my child.
if you need help go to your GP or A&E.
stop harassing me .
