Personal RP crisis?

Lately I am not happy with my roleplaying in DD. I find its neither witty nor does it always make sense. I find it a struggle to play true to my character bacause lately my character is in some sort of crisis and she is unsure who she really is. I notice that I am playing not as bold as I used to. I am very careful lately and get insecure about everything, even about the fact that I am not a native speaker. Also I do a lot of typos. We've got a lot of very good roleplayers at DD and I fear I am not up to standart. I don't know why I never worried about all this before. I just hope I get over it soon.
