No apologies are necessary for your English. We get letters from all over the world. You did fine.
You already had a successful experience with a therapist. I suggest you return to the provider you were seeing for another evaluation. That person already knows your story and knows what was helpful.
You are correct to be concerned about the return of symptoms. But I want you to know that it is not unusual for a client to have more than one episode of depression and to need another episode of treatment to address it. It is also not unusual for people to return to their therapist for periodic “adjustments” or fine-tuning.
Please take care of yourself. Go see your former treater and get the help you need and deserve. There is no reason for you to continue to suffer.
I wish you well.
