Sometimes the treatment can be worse than the problem. Weigh up if your life is really at risk before you give in to taking such strong medication. Your family is right to be concerned over medication like this. GPs are not as trained in mental health as a psychiatrist and even therapists should not be giving out diagnosis's like that. You really need to see a psychiatrist for the best treatment for yourself. Are you sure there are no triggers to your moods? Have you done any mood tracking? How is your diet and lifestyle? There is so much you need to ask yourself before turning to medication. Be cautious. Meds really can cause more problems for people who do not truly need them. Be absolutely honest with yourself before taking this step.
