The Paisley golfer tees off in the South African Open tomorrow, his final event of the year, needing a big finish to safeguard a place at the top table.
Forsyth, 36, who is currently languishes in 133rd spot on the money list, needs to break into the top 115 to retain his playing rights. The two-time Euro Tour winner began his season with a fifth place finish in the Africa Open back in January.
However, after that flying start, Forsyth, who has been plagued by a niggling wrist injury, has come crashing back to earth in the months that have followed.
The former Scottish PGA champ said: "I've had 16 tournaments on the main Tour this season and that should have been more than enough to secure my card.
"I only have myself to blame.
"I've made a lot of cuts, but haven't taken good enough form into the weekend.
"It's difficult when you are dipping in and out of tournaments because you are always chasing your tail.
"But that's where I am now and I have to get on with it."
Forsyth will be joined in the field by Colville Park's Steven O'Hara, who failed to progress past stage two of the qualifying school in Spain last weekend, but has one last chance to save his Tour card this week.
Glasgow's Marc Warren also lines-up in South Africa and, at No.52 on the money list, the double Tour champion is on course for a spot in the season-ending Dubai World Championship.
In the Far East, Glasgow golfer Scott Jamieson, 56th in the rankings, will tee-off in the UBS Hong Kong Open looking to cement a place in the top 60 and qualify for Dubai.
Scotland's ryder Cup star Paul Lawrie is also taking in the Hong Kong event.
