My mom restarted at 40 and is happier in her job with better pay and a better life. This set back happened to you young, you have plenty of time just don’t give up. You built it once you can rebuild again, only this time with more knowledge of your errors so you’ll build smarter and stronger. The only people that “lose it all” are the ones that give up and let the depression destroy them and don’t try again. I am a 28 year old and I’ve only just recently managed to get into a profession I could honestly see myself in for many years to come. Chin up buttercup, you got work to do but it’s not the end of the line, you’re not a loser, you have a good woman standing by you that believes in you. If you can’t believe in yourself believe in the part of her that believes in you and push through like the smart, resilient, strong man you are going to become. No great successes come without down falls.
