All these things take a huge toll, the diabetes thing goes hand and hand with under active thoyrid, thats makes you letargic and contributes also to the hair loss, get a thoyrid function test done, if it is all you to do is start taking eltroxin. At least visit you gp and discuss it even talking can help. The worst thing anyone can tell you now is snap out of it, if only it was as simple as that. I am going thru a very bad patch myself at present but fighting it hard. keep talking it does help. I would also like to thank sargie for starting this thread well done m8.
