sorry i didn't know what forum to place this in. Its a mental health problem so ive placed it the health forum. My brother has become consumed with fear that theres going to be a nuclear war. He can't sleep, he's not able to go to work because the fear consumes him 24/7. He is starting to having problems with his marriage. The fear/anxiety is starting to drive paranoia. I don't believe he's mentally ill the fear is based on some rational rather than irrational but i worry the he might become mentally ill and suffer from a mania or psychosis under the stress. I have tried to reassure him that nato aren't putting boots on the ground or a no fly zone in Ukraine but other than that i don't know how to reassure him that there isnt going to be a nuclear war. I was wondering if anyone could give me any advice on what's the best thing to say to reassure him and what medication he probably needs. He is trying to get pills for his anxiety but i didn't know if maybe he needs a low dose of an anti psychotic to prevent a mental health episode developing. Some of his thinking driven by paranoia has no rational but i don't believe at this stage he is showing any signs of a mental illness Ie he doesnt seem manic or to be suffering from psychosis. Any advice on what to say or suggestions of possible medication would be greatly appreciated.
