I learned that I didn't always have healthy relationships with people due to codependency. People that weren't really good friends or partners, I kept in my life because my self-worth was contingent upon them even though they weren't nice to me. My behavior was due to my low self-esteem and depression.
I first started by improving my relationship with myself. Speaking with a therapist, using positive affirmations, and developing healing practices are all currently helping me to re-connect with who I am. This work has made me re-evaluate what I believe a true and good friend or partner is, and I've found a small number of people that treat me with the kindness, dignity and respect that I deserve (outside of my family). People that I feel comfortable enough to be vulnerable with, while also setting healthy boundaries. There's only a handful of people I have like that in my life. I prefer to have deep, meaningful connections with a few people than superficial connections with many people.
Definitely easier said than done! Self-care and healing are so important. I believe when we incorporate those elements into our lives, our lives become simpler because we have a deep sense of self-awareness. To incorporate into my routine, I started by using Maslow's hierarchy of needs to determine what area of self-care to focus on first. For me, it was love and belonging. I re-evaluated my friendships and focused on forming relationships with people I deeply connect with - step 2 listed above.
