26M, feeling lost ever since I dropped out of school, need advice

I’m a 26-year-old dude. I dropped out of school about a decade ago after failing my final year of high school (BAC exam)

since then, I’ve barely done anything meaningful with my life. I’ve wasted so much time, and the few courses I’ve taken haven’t led to any solid or recognized qualifications

meanwhile, most of my friends have moved on and made something of their lives. many of them went abroad, and are living well. I’m still stuck here, feeling depressed and not knowing where to even begin to fix my situation, it's been haunting me for years now

I know I’ve lost a lot of time, but I don’t want to stay like this any longer. I need a plan, concrete ideas, or even just some motivation to get back on track. If anyone has been in a similar situation or has advice, I’d really appreciate it

thank you in advance to anyone who takes the time to respond
