Greetings! Well it seems like this person that you are talking about has developed Depression and anxiety as a result of the stress of loosing his job and as it usually happens in these conditions he is not being able to counter these on his own and slipping deeper and deeper in them. So I suggest that he needs to be shown to a psychiatrist and started on an anti depressant drug such as Escitalopram at dose of 10-20 mg / day or sertraline at dose of 25-100 mg / day starting first on a lower dose and then titrating up the dose. Along with the anti depressant drug he also needs to be put on an anti anxiety drug like clonazepam at dose of 0.25 mg twice a day. So to summarize his conditions of anxiety + depression need to be assessed by a psychiatrist and thereafter he needs to be put on a combination of 1 anti depressant and 1 anti anxiety drug for a period of at least 4-6 months for full relapse free recovery although it may so happen that he shall recover within 2-3 months of use of these drugs but still full course as mentioned above needs to be completed to prevent relapse of the symptoms which is quite common an occurrence if the complete treatment is not done. I hope this helps. Regards
