Hey Dad, I fucked up

Dad, I (25M) haven't really made any momey after you sponsered my move to Canada for studies. Honestly, I expected this country to treat me nice financially, I promise that I applied for over 400 jobs throughout these last 1.5 years, but I only got 3 responses by far, and it has taken a toll on my mental health. (Depression - Bedrot for last 2 months) Thank you for supporting me with my living expenses as well, the B2B sales program that I am enrolled in will be completed by April 2025, but I don't know how to find work. They say it's the economy, but I have seen much inferior skills getting hired, what am I really lacking? Any suggestions?
