Lucid dreaming is good for overcoming fears and issues in a way that isn't possible in waking life. If you have a way that you can possibly deal with the issue in waking life, you should do it in waking life rather than waiting for a lucid dream.

If you're having trouble distinguishing between what is real and what is not, then you shouldn't be doing anything dangerous during a lucid dream, especially if it's a false awakening.

My advice is to stay positive, let the symptoms be, and and seek professional help if the they persist. Also, if you're pushing away thoughts of fear, you should be prepared to have nightmares when sleeping. Try to stay as calm as possible if you have one and try to learn from them if you can. This is more constructive than being scared and trying to supress them. For example, if you're having a lucid nightmare, have a nice chat with the scary looking DC rather than trying to run away from it.
