What Should I Do (some boss name spoilers)

So currently Im level 47 and my weapon is +5. I'm in a bit of a rough patch right now. Wolnir and the demon king both gave me trouble and now that I'm in irithyll of the boreal valley, I'm beginning to lose the will to play. I felt that the game has been hard but fair consistently so far. However, I have been noticing the rapid increase in difficulty. First the cathedral gave me some trouble, no big deal though. Then the catacombs was worse, and my excitement was faltering. Now in the boreal valley, and I'm not feeling it anymore. I feel like every singular enemy is doing insane damage to me and I have to fight like 3 at a time. I'm not angry, I don't really get angry playing souls games. I'm just sad because I feel like I'm not making any progress and even the shitty enemies are killing me. I don't know what to do. I don't feel like exploring anymore because I know what comes next will be even more difficult and I'm not in the right mindset to deal with that. Am I underleveled or am I just bad.

TL;DR should I grind or git gud or both
