There are various signs that you may be struggling with codependency. The most common signs are if you always feel worried about feeling abandoned or alone, sticking with someone who mistreats you and does not respect you, and feeling like you cannot live with others. If you are in a codependent relationship and would like your relationship to overcome the co-dependency, know that it is possible.
Talking to a therapist will help you find out why you may be struggling with codependency and how you can better yourself. There they will be able to give you more guidance and help to fully restore yourself. Most importantly though, know that co-dependency is very common and you should not feel discouraged to ask for help or guidance.
