How about going a bit more specific? Instead of the broad self-esteem goal, how about something like learning to recognize and give yourself credit where credit is due, or maybe becoming involved in one activity that will be self-affirming. (For me that might have been starting an affirmations journal or going back to church choir.). Instead of managing anxiety, how about learning three specific techniques for calming your mind. (That might be yoga or mindfulness or breathing techniques, etc.). If you can make your goals more concrete, they might seem more achievable.
