Buddhism is kind of depressing

Please correct me if I'm misguided about this but I was doing some reading which seemed to be saying that life on this earth is nothing but suffering. That while we are ignorant we wander around in samsara experiencing the pain of birth, ageing, illness and death etc The goal is to be free of this cycle by reaching nibanna and not be reborn anymore. I don't see the point. Because if I am no longer reborn then where am I? If I don't exist anymore then I cannot be in nibanna. And if I no longer exist then what is the point of getting to nibanna anyway as I won't be able to experience it. I feel that this view is somewhat depressing. It makes me think what is the point of anything. Why bother even trying to accomplish or achieve anything if it's all suffering and the goal is to not exist anymore?
