You drop it, seriously drop the game. There are other games out there that will fill your needs, if you want a similar experience try playing borderlands. I have the same issues as you, I also play alone and when I just cant do something ill look at the forums or do my best to convince some old friends to help out. The majority of the time I just cant do much so I play other games. Do you play on pc? Have you ever thought about modding games? I have heavily modded my skyrim and I feel I’m playing a completely different game. You can mod Witcher, and other titles, once you learn to mod, it becomes a game in itself because the possibilities are endless
