Not really. It's all been coping mechanisms and trying to get through the best I could. I've had happier periods in life but, nothing consistent.
Did you OP? Are you sure there's no way of getting back to it? I've never been able to decide which was worse. Someone who did have an enjoyable life. They would have something they could aim to get back to. I imagine that would be more motivating than someone who's never experienced a satisfying life and, doesn't believe it exists. On the other hand, if they truly feel like they can't get back to it, it's got to be so bittersweet.
