The mental health of Gazans has been badly affected by Israel's war on the coastal territory [AFP]

Palestinian men have been hit especially hard. Many of them have spent the last two years struggling to find work under Israel's blockade of the territory and the horrors of the war have made things harder and more traumatic.

Al Jazeera's Zeina Awad reports from a mental health clinic in Gaza City.

He lost everything when Israeli missiles struck his home, his sewing factory, and his garden.

He says he has lost his will to live and he finds it hard to get out of bed. He describes his life as a "dark tunnel, with no light in sight".

"I spent years working hard and saving money to buy my sewing machines, one by one, to build up my business. It was all gone, just like that, in a second," he said.

"I don’t know what I am going to do."

Business impossible

Fouzan's problems go back to when he lost his clients abroad, as Israel tightened its siege on Gaza and made it impossible for him to export the clothes he was making.

As his situation worsened, he was forced to sell equipment and furniture just to put food on the table. And when the war started, it took away all he had left.

Gaza assaults fuel mental health crisis

"What was I supposed to do? I was scared, but I would control myself to make it seem like everything was okay.

"I don't sleep, very rarely, maybe a couple of hours per night. I am constantly worried. Even if I wanted to get out, to take a break and go somewhere to forget a little, I can't because the crossings are closed.

"I can't even take a walk along the shore because there are warships in the sea the whole time and they may aim at me," he said.

'Only relief'

The Gaza Community Mental Health Programme (GCMHP) is the only relief that Fouzan is able to get.

He has been a patient there for over a year and sees his doctor twice a week.

The GCMHP, Gaza's largest mental health clinic, employs nearly 30 psychiatrists, psychologists, social workers and nurses.

Fouzan's livelihood has been destroyed  by the Israeli attacks

Dr Eyad Sarraj, the director of the GCMHP, said: "Adults are the symbol of protection, providing and power for the children.

"Adults have already been lost as providers because of the economic siege. During this war, they were lost as protectors.

"Children were looking up to them to ask them, 'Where is a safe place? How can you protect me?'

"Some felt defeated as men, defeated in the struggle because they could not defend their children."

Saraj says that at least half of the people living in Gaza need professional help to cope with the war. Many of them have a constant feeling of insecurity.

Like Fouzan, they live with a sense of collective trauma, built up over years - and even generations.
