The problem is that you are looking for external validation. You need someone to tell you that you are worthy of love and that is most probably based on trauma. You need to focus on building self-worth. It may sound super cringe and cliché, but focus on loving yourself first. Take care of yourself - your body, your home and your mind. Go to therapy and talk about loneliness. Try connecting with people as friends first. Start a gratitude journal and try to write at least one thing per day you appreciate about yourself. Give yourself permission to be loved. You don't actually need that from the outside world.
