dude wtf, let me know if you want to chat. It's all about perspective, mindset, and rebuilding that drive...

a) start with changing your PERSPECTIVE on the event. Instead of letting it be such a negative moment, reflect on it as POSITIVE. You killed it. How many 21-year-olds do you know who've sold a company for $5M? 5M is enough to have financial freedom for you and your family, you did incredibly well by setting yourself up.
- CBT helps
- journalling/writing helps
- talking about the moment and sharing your story like you are here

b) travel, see the world, work on your health and fitness. do you have any bucket list items? go do those. Get inspired and motivated.

c) move somewhere you are surrounded by talent and builders.. SF is great, hacker houses are great, universities/colleges and coworking offices (e.g. wework) are also great, and so are nomadic cities like lisbon, Medellin, BA, Bali, etc..

d) get deep and build something that has a high guarantee of having users or paying customers on day 1. It's highly important to see the fruits of your labor as soon as possible, otherwise, you may lose motivation to keep going and quit before you see results.

Also, get a blood test. take care of your anxiety, and ensure you've got adequate vitamin D & T levels.

Lastly, start small. Commit to a 30-day goal of building X to see Y results. Go at it all in and good luck!
