I struggle with this too. It's important to learn how to set healthy boundaries otherwise it becomes very difficult to deal with, with time. Spend time around people that accept you as you are. Be careful about recognizing other people's emotions and opinions as theirs and not as your own so that they don't cause influences on you. Get out of unhealthy situations and relationships fast and take what you can learn from them. Avoid toxicity and never doubt your potentials to heal and grow.
