Hey, hang in there Mr Alien. Sometimes disillusionment is a good thing as it's telling you something isn't right - listen to it. Then when you've listened to it and the reasons for it, decide where you are going to go next, maybe in new directions you hadn't thought of. Think of it as an opportunity and a challenge, not something to be defeated by.
As for the negative folks, there's always going to be these people who project their negativity onto what you do. It's their choice and it really has nothing to do with who or what you are or what your project is or how good it is. Remember that self esteem is about how YOU value YOURSELF, it has absolutely nothing to do with what other people think of you or what you create. For the most part, constructive criticism can be useful to an extent, so long as it is not stuck in being negative for the sake of it, otherwise it is unproductive and unconstructive.
Also maybe you need to step back, take a bit of a break and relax for a while, ponder things, get some space and find some inspiration.
