Debbie I think you will just have to accept Lizzie as she is, you can keep trying all the positive things and see if she changes any, but I believe it is just her personality, I have had my Lexie coming up two years, and still she is timid and strange at times, she is a real love-bug as well, but she is a scaredy cat for sure, maybe something happened in her past to make her this way, but maybe it is just the way she is, she still runs like heck when she see's my son, we have no idea why, he has never hurt or been mean to her in anyway,he will pick her up and kiss her and cuddle her, and she will just put up with it(being held by anyone is NOT her favourite thing) and when he puts her down she looks frightened and runs away, infact my Lexie has really only trusted my husband in the last few months, so it all takes time and really you should not feel bad, you are a great furmummy, just be patient and keep trying and good luck.
