Thank you everyone, I didn't expect to get this much support, and honestly, I've been wanting to share this story for a while. I'm going to follow up on most people's advice and cut this person out of my life completely. I believe that if I do that, things will get better for me in the future and I can begin to focus on what matters to me the most. I won't be attempting to confront her like a few people suggested, but only because I have now learned that she 100% does not care about me, and it would really be a waste of my time and patience.
I'm not giving up on Block Wars because they have beaten me. I'm making this change because I simply don't enjoy the game anymore, and I don't see any reason to continue playing a game I don't enjoy. There will be no more grinding wins in any game, I've decided I'm going to be online when I feel like it, and play more than just one game too, because the obsession I had with Block Wars was certainly not healthy and was doing too much damage to my mental health.
So, I am hoping to become more active outside of the network, such as on Forums and also the Discord. Some may have seen me there already, but thanks to this thread it occurred to me that there are so many players who are worth having as friends, but I've been so involved in Block Wars that I have failed to meet them.
I tried not to make this into an essay, I swear I did, but I couldn't do it! I hope that you still read this even though I didn't respond to each person individually. You are all so caring and understanding, and I wish I had met some people like you sooner in my time on CubeCraft.
(Sorry if you didn't want the tag, I just wanted to make sure people knew I’m grateful for the support!)
