Mood swing, is it mindset or a real problem?

I've been struggling for social anxiety for years now. Fortunately it has been getting better, but some bad thoughts (and memories) can still trigger me to be scared, it got me into a real bad mood just in a split second.

Sometimes, i don't even understand the cause of my bad mood. I can be that outgoing, silly, and kind person people just love to be around with, and then with no apparent reason, my mood just dropped. I avoid social interactions, i trust nobody, I feel that my voice is just unimportant for those around me. I feel nobody respect me and nobody would ever look up to someone like me.

I feel like I always do something wrong and stupid, and that people just dislike me. I feel like I can't really survive as a person who has lots of ambitions and goals in life, even though my goals are mostly for other people, how can i make others feel and live better If i can't even control my own emotion.

It's just a matter of mood, but it does effect who I am and the way I act at that particular moment. It's just simply hard to lift my mood back up again.

I can relate.. If you've been struggling with anxiety for years, then I think it's perfectly normal for this to happen. Just keep getting better, I'm sure you did a good job so far
