Need advice

I feel like I’m becoming someone I’m not and I’m not okay. I tell my bf every single emotion I feel. He has been very supportive but I still feel like something is wrong with me. I google every symptom and try to diagnose myself. Idk what to do. Im cautious about what I say and how I say it. I’m tired of living my life in fear. After our son it’s like I don’t know how to be happy and live in the moment anymore.
