One thing you will learn is that it's drive that pays off. If you feel like quiting in the bad times during startup you're going to have a hard time when your company runs into hard times in the future once you've invested more into it. Look at the guys form airbnb, they lived of cereal and were broke but they never lost hope. Like bradly said find some like minded roommates. Also congrats on having investors contact you, thats a good sign. Keep it up.
