I've stayed off this thread because it's too close to home at the moment. I have a very near and dear relative who has been suffering from depression for four years. Deep, dark overwhelming depression. The sort where staying alive every day is a struggle.
He believes in self-help, as do his family insofar as it's possible, but we were beside ourselves when well meaning friends 'encouraged' him by telling him not to 'resort' (verb: turn to and adopt (a course of action, especially an extreme or undesirable one ) to medication. Instead, mindfulness, counselling, St. John's Wort and yoga were all recommended by people who thought they knew what was needed. Meanwhile, those of us who do know him really well were desperate for him to see a GP and were praying that he would get medication. He finally, and with great reluctance, did go to his GP and was given antidepressants.
Recently things have been so bad that he asked his family to step in and help him to stay alive. After intervention from family members he has now been seen by a specialist mental health team: they have prescribed a different medication, long-term intensive CBT with a very senior clinical psychologist, a full psychiatric review, and he's also been deemed in need of regular supervision from the Mental Health Professional at his surgery. All much to the surprise of his friends who are now saying how shocked they are because they didn't realise that things were so serious!
My point is that however well meaning we might be, a GP is usually the person most qualified to assess and diagnose appropriate courses of action for someone presenting with symptoms of depression or anxiety. Go and see your GP holdthetonic, then come back on here and tell us how we can help you to keep your head above water.
