Reflection after exam posting psychiatry.
In all psychiatric patient, either anxiety disorder, depression disorder, bipolar disorder, it is very vital for all of them to have a good support system in order to pull them out from that phase.
Losing/not having a good support system, will cause them to dive even deeper into all of their phases and worsen the disorder.
So if you see your friends need help to share their problem, just be there and hear it. Even though sometimes you cannot do anything to help them, but actually listening to them is the biggest help they ever get. .
They need someone to hear them and share their problem. And also maybe some support from the people around them. Try to take them out, be socialize, go watch movie, go kenduri together so that are not dwelling with the disorders.
InsyaAllah may Allah help you and your friends with that disorder.
