My company is funded. Solo Entrepreneur. Have to raise $3M-$5M to go into production. Multiple leads into due diligence, no closings. Morale is low. Trudging. Drinking too much. They say keep at it with their support – all just words.

For sure drinking wont help. Stop it and decrease risks for yourself.

investor leads, you mean? if so, that shows interest. meaning, you have something. $3M-§5M is a lot but remember, you only need one. "During this time I learned the most important rule of raising money privately: Look for a market of one. You only need one investor to say yes, so it’s best to ignore the other thirty who say 'no.'"

Yes, everything is just words, but after all you're the only one that can make anything happen. So take those words at face value but also be encouraged by them since people seem to be believing in you and your vision.
