Hello thanks for asking from HCM for your health related queries
I can understand your concern. You have
major depressive disorder and have taken treatment for years without much benefit. Currently you are on Prozac or
Fluoxetine which is a SSRI drug. The drug is a good antidepressant drug but even with the high doses of this drug your symptoms are persisting. The symptoms like feeling isolates, hopelessness (nothing to look forward in life), remaining at home alone, helplessness in solving your problems are persisting symptoms of depression.
In such situation I'd recommend you to visit your
psychiatrist again and discuss about the proper treatment of resident depression. In resistant depression medicines like Lithium,
Lamotrigine, Bupropion etc are used along with SSRIs or SNRIs. These medicines augment the actions of the antidepressants and help in quick recovery. Apart from this associated
cognitive therapy can also help. Cognitive therapy along with medicines provides best results in depression. Visit your doctor for help.
Thanks, I hope this helps you.
Take care
