It’s just a game, but I’m so hard on myself for not being good enough

I feel dumb for making this post but I don’t know why this has been making me feel so bad lately. I started playing World of Warcraft in July, and I absolutely love it, but I’m still such a newb compared to my husband and his friends. We often all play together, and naturally I don’t do as good as them and it sometimes feels like they expect me to suddenly be an expert with years of experience. It doesn’t help that yesterday I overheard them talking about how I didn’t do good. I mean they do make an effort to help me and include me, but it still bothers me. It’s even more frustrating when I feel like I’m doing pretty decent only to find out I didn’t. I mean there have been a few times where I even did better than them, but they never pay attention to that and just chalk it up to luck. I feel like I’m pretty good for such a short time, but they always expect more. It makes me feel like the girl that can’t fit in with the guys :/ I wish they would stop assuming that I’m doing something wrong and realize that I just need practice with muscle memory, which can only be improved with time. I spent a lot of hours learning proper techniques and they still treat me like I don’t know what I’m doing sometimes. I don’t know why I keep getting so down about this and taking it so personally, when I know that they still like playing with me and often ask me to join.
