Brief Answer:
This is the bereavement reaction

Detailed Answer:
Hello,
Thanks for using Healthcaremagic.

I read your query and understand your concerns.

I do not feel it is nervous breakdown but there is clear evidence in favor of stress having a toll on his life and your relationship. Behaving in such a way is commonly seen when we are under huge stress but lasting of same thing for last 90 days indicates there is need to seek help.

In my clinical practice I see patients who deny something bad happening followed by regression and blaming others although their inner knows that nobody can be blamed.

His behavior like a 11 year old (regression) and blaming you for everything is indicative of immature defenses under stress,

In addition there may be direction of anger toward you which supposed to be directed to his abusive father. This also happens when we have two opposing forces in our mind. (Love toward father versus anger toward him because of his abuse=ive nature and abandonment).

Having said this I like to say that rather than panicking with his behavior you need to be supportive to him so that he can better manage his stress of terminal illness with his father.

In addition to this seek help of psychiatrist/psychologist in your city as soon as possible so he can be helped out as soon as possible.

I hope this helps you.
Thanks and regards

Brief Answer:
Possible

Detailed Answer:
Hello,
Thanks for reverting back to me.

With use/abuse of cocaine paranoia is one of the common manifestation in which person feels that he is dealing with people who are against him/his interest.

I am not aware how long and how much cocaine he is using but in case he has sudden increase in dose in compare to past or if he is using for years chances of severe paranoia are high.

Having said this the urgency to seek psychiatric help is more considering his cocaine abuse, severe stress and his current symptoms.

Hope I am able to answer your concerns.

Hello,
Thanks for follow up.

Since the both factors are probably present, the risk of cocaine induced paranoia is higher.
In every context it is possible that he is behaving in such a way because of cocaine abuse and other co occurring factors.

I hope this helps you in taking informed decision for his treatment.
