Yes, your experience probably does play into your jealousy of sick people, but no, such jealousy does not make you a horrible person. Your jealousy is very understandable and simply an indication how much you're hurting. You didn't get what you needed while growing up, and you're kind of stuck there. Your therapist can help you deal with this and move on to a better place. You won't be judged. That's not what your therapist is there for. So, give it a shot. Let her know what's hurting you.
