(I am not saying this forum is bad, knowledge here is very high
but Im saying this simultanoeusly boring and strangely and strongly demotivating (at least for me ;/))
If it's really bad enough that you feel like you're oppressed or that you've wasted your time on this board, then maybe you should do what you feel is best for you. What else do you suggest? Most of us aren't psychiatrists and can't diagnose demotivation issues, so unless you have specific problems with the forum that you want looked into in order to feel better, nobody can really help you, and while the gamedev community is what it is, it (like everything else) can't please everyone.
PS: I am sure this is obvious but you don't need to spend 100% of your time on gamedev - it is in fact possible to be active on multiple forums at once, which might alleviate the boredom you are experiencing. Maybe try widening your interests, finding a new hobby, or getting involved in another community (not necessarily an online one), perhaps you will find a community that you can spend more time with that isn't as "boring" to you as here.
