Everyone has problems, and I know exactly what it feels like to feel unsure where money will come from, how the bills will be paid. What you can't do is do nothing. Take action, get moving, and fear fades to the background as you reclaim your life.
Remember this one thing;
Action leads to opportunity.
All the things you try, these are experiments not failures.
As you test the waters and try different products, remember that if they don't work, they are not failures, they are experiments on the way to success. I read a quote once, and I am not sure who wrote it but to paraphrase, if it is not working, it doesn't mean it will end badly, it just means the work isn't finished.
