Role-playing? I try…

When it comes to RP’ing I’m not as good as others. I try my best but I get so nervous and feel like I’m not playing the character correctly, even if I know the characters well. Just now I attempted a Sherlock role-play where I played the part of good ‘ol Dr. John Watson. I played his part to the best of my ability, however I fear that I may have made him either not emotional enough, or that I have given him the appearance that he’s a soul-less jerk (I’m kind of exaggerating with that…). Near the end of the RP I apologized in case I had not played the part up to par. The other person told me not to worry and said that I had done well. I would agree with this statement, however I have so many doubts. I do not doubt my writing skills, I know I am very creative and I use proper grammar and punctuation where I feel it needs to be used. However I always seem to struggle with the “John… John I’m so sorry - SH” statement. I play along and I know how John should be reacting. But I know if I make him react too much he’s like a blubbering baby, yet, if he reacts too little he appears that he never cared for Sherlock. I know all it takes is practice and I really do want to continue trying… But for now in these awkward stages of “newbie rp’ing” I’m so nervous that I’ll make a mistake. I don’t want to upset the others who are actually good at role-playing… I hope they at least know I’m trying.
