Hey dont be sad, my security started on around march 18 and my final decision done by april 07, so when they start it, wont take months, is just need to be started, two, three weeks. I waited for 32 months and my dependants are also overseas, you are not alone, but let me tell you there is hope. After my ecopr received , 04 months later my dependants received the passport requested. So cheer you up, you already waited the most.
Just an advice, try to keep alive your file, call IRCC ask to the agent if can make a note on your file. I asked that once and my fie started moving.
Hugs and my best wishes for you!
