The Dolphins went down 2-1 to Hampton & Richmond in midweek to leave them five points adrift of safety with three games left.
Killick’s side know that if Hungerford Town better their result this weekend, their stay at Step 2 will be over.
However, games against fellow strugglers Concord Rangers and Oxford City - and relegated Whitehawk - will all be seen as winnable and Killick reckons his side are much stronger now than earlier in the season.
“We couldn’t get the result we needed on Tuesday, which was made worse when Concord’s result went against us,” the boss told the Daily Echo.
"I didn’t fancy them to lose against an already-relegated team in midweek so I expected to be in a similar situation.
“The difficulty is Whitehawk go to Hungerford. We have to try to beat Concord and see where it would take us.
“If we'd had the side we have available now all season, we wouldn’t be in the position we are. That’s another factor and the players can’t be blamed for that – it’s my fault.”
