Should I give up?
drawkbox: Just pick up a day job again if you can or find some other revenue streams.  You launched it full-time 3 months ago.  If you maybe made that move prematurely then just go back into that for another 3,6,12 months.  Don't quit your day job until you have enough to live on.However if you are having the feeling of quitting, you need to decide if you want to throw away the last couple years as a try and try again another way.  Sometimes ideas and failure make you better the next time.  But also it always gets harder before it gets easier.
