I actually found peer support groups (run by people who have their own history with mental illness) to be far more helpful to me than therapy with a trained counselor. Many of these are also free and available online to people from all over the world.
I also joined Overeaters Anonymous and I really find the 12 steps helpful regardless of whether or not you have an addiction. They have Emotions Anonymous for people with mental health issues to do the 12 steps.
The pandemic actually opened up more avenues of support to me, because I can attend meetings hosted all over the world.
