I say do it
Take real steps towards growth. Do things you are afraid of, because stepping outside your comfort zone is where real growth takes place. One of the best remedies against low self-esteem is pride - pride in your efforts, your growth and your achievements, no matter how small. Treat yourself like a good friend; be kind, encouraging and supportive of yourself. Accept compliments with a "thank you" and ask yourself, "If this were a good friend, how would I react?" So why not treat yourself the same way?
