Please don’t minimize your experiences. I understand your frustration. I’m sorry you aren’t feeling better than this.
The place to start is with your current therapist. Have you shared your discouragement with her? It may be time for your therapist to change the focus or the method of her treatment. If that doesn’t help, do consider seeking a “second opinion”. It may be that a different approach all together would be helpful.
In addition, some direct personal work on building up your self-esteem may re-energize your treatment. The secret to gaining more self-esteem is to stop thinking about it and start doing worthwhile things. If you wait until you feel better to start your life, it probably won’t happen. But if you start doing things that matter, the successes will help you feel much better, which will give you more energy to do more.
If you don’t feel ready for a paying job, then by all means find a volunteer position. Doing good work makes people feel good. An added bonus is that it will help you get used to a more structured day and will give you an entry for a resume. Thoughtful volunteering will also help you experiment with different kinds of work. Being appreciated for what you contribute will add to your feelings of self-worth.
I wish you well.
