Families are still looking for their missing relatives, others demanding their land back from military occupation, fishermen asking for sea access blocked by the navy, widows heading families and handicapped persons are struggling without jobs. Rehabilitated ex-rebels are shunned by a society that once glorified them.
Lawmaker Abraham Sumanthiran said "a sense of uncertainty is hanging over the people."
Sumanthiran belongs to the main political party representing minority Tamils who bore the brunt of the civil war, which ended in May 2009 with the defeat of Tamil Tiger rebels at the hands of the Sinhalese-dominated government.
A court, however, barred Tamil activists from holding a commemoration near a monument in the country's former northern war zone to Tamils killed in the fighting, but other ceremonies were carried out unhindered in many parts of the north and east.

Tamils in the north complain that the government continues to have a heavy military presence there despite an absence of violence since the end of the civil war. But Sirisena vowed today to increase the military's strength.
People had hoped for better times with the election of Sirisena, who in 2015 overwhelmingly defeated strongman leader Mahinda Rajapaksa, who led the war effort.
"More than Mahinda Rajapaksa, the people are angry with the current government because the people did not expect him (Rajapaksa) to do any good," said T. Paranthaman, who works with the war-affected in the Tamil-majority north. "People are getting fed up. There is a lot of mistrust that the Sinhalese-dominated government is not going to give them anything."
Relatives say they personally handed them over to the military in the last days of the fighting after the military asked those with the least connection to the rebels to surrender.
No steps have been taken to establish a judicial mechanism to investigate allegations of serious human rights violations and war crimes against both the government and Tamil Tiger rebels, despite pledges to the United Nations Human Rights Council.
Dozens of people arrested on suspicion of links to the rebels have been detained for years without being charged and the anti-terror law, criticised as draconian and which the government promised to replace, is still in place.
According to a UN report, some 40,000 people are believed to have been killed in just the final months of the fighting.
The rebels are accused of recruiting child soldiers and exposing people to danger by holding them as human shield and killing those who tried to escape their control.
