I'm also a financial advisor with a tech startup.
It's just money. Money doesn't do anything, so don't love it. However, your responsibilities with it just rose far beyond what you were prepared to handle. Take your time and find a professional. If you want to learn to do it yourself, find a professional who will teach you.
The job produced the money, but there is still work to do as a man. So plan to work. Work is hard, but work is where the meaning lies, not the money that the job pays. Is also important for your kids that they see you work.
You have reason to be concerned. Many would stop working altogether. I've seen it over and over. They end up with all the vices.
Plan to work. If you like what you're doing, keep doing it.
