27 years of insecurities, self blame and fears… when all that has a name and there are a lot of people like you, facing the same downs like you. All these years were actually not about your incapability but about you not knowing how to correctly cope with what you have. There are people with exact your problem, people learn how to live a full life and enjoy life as it is.
Be positive, focus on what can be done. Trust yourself, your body. Don’t expect too much from medications, sometimes even doctors don’t know exactly how that stuff works. Listen to your guts and accept yourself, that’s a first thing to start with.
