You can try Amaha or BetterHelp. I’ve tried Amaha, and it’s good. Usually charges 2000-5000 for a one hour session depending on the therapist. Also, make sure that you’re consistent with Therapy. Because the first session is usually about the therapist trying to understand more about you situation, your personal/professional life, etc. It usually takes 1-2 months for the therapy to start taking effect.
You can go with an hourly session for the first one, and then half hour sessions every two weeks. And I understand that you’re looking for online, but physical sessions usually work much better, since the therapist can better read your body movements when you’re talking or listening.
I hope you get through this and feel better soon. :)
