I'm really sorry to hear that. It’s frustrating because they often delay files for what seems like no reason at all.
You could look into applying for mandamus to force a decision, but be careful. I’ve heard recently that if your file is stuck in comprehensive security screening, the court will likely rule in favor of IRCC. Their argument is that national security checks are out of their hands and managed by secondary agencies like the CBSA and CSIS, so the judge usually gives them a pass on the delay
