Develop positive attitude, tenderness, natural attraction.
Write notes to yourself, read them every day to remind yourself of what you need to hear most. Cut off the negativity, unfollow people that make you feel bad about yourself, stop communicating with those, who drain your energy. Do not waste your energy of judging or gossiping about other people.
Experiment with your hairstyle, wear accessories, dress up for yourself.
Let yourself be sad or unproductive for some time only to replenish your strength only to return stronger than ever.
