I forgot I wanted to reply to this thread when I first saw it but was really frazzled with work at the time!
First, congrats! It's always really really exciting when folks who aren't already in the entertainment business circle get something across! And that's really all it takes sometimes is a friend who passes something along!
Second, I'm actually in a similar situation as you right now with one of my comics and have been in this weird limbo for the past, like, 2 years? So I just wanna say don't feel discouraged by how long anything takes. It takes even very well known and established actual entertainment biz people YEARS to get approval on projects. The important thing here is that YOU are now someone THEY know. Your name and your work is in their heads now and that might not mean anything immediately but it can pop up somewhere down the line when you least expect it and that's HUGE!!! HUGE!!!!!!!! Even if you end up in the same limbo as me or nothing ends up coming out of it that's better than what most people can hope for and its still a potential opportunity in the future.
Third, as a person who used always feels like they don't deserve any chances; that is NOT up for you to decide. You are worth taking a chance on because you have people willing to take a chance on it and that is the only parameter that matters. In situations like this, you don't get to decide whether you deserve it or not because people have decided that you do deserve it. Clearly, you have something that you may not see but they do!
