This "I'm going to kill myself" crap has got to stop now. Here's what: write a letter to the police department of his town, general attention. Tell them your father's contact details and name the times in the last two months that he's threatened to kill himself. Tell them that in his latest threat he said he was buying a gun. Tell them that you've blocked his numbers because he always threatened, then backed down, and you were finding it extremely traumatic. Keep a copy of the letter for yourself.

That way your conscience is clean, and it's out of your hands. DONE.
