anxiety
"I've always had problems with persistent depression since I was 14 (I'm now 25) but I've never been suicidal. It took me a couple of weeks to realise it but this medication made me suicidal! I was prescribed it for anxiety and restless legs at night, it did get me to sleep but I woke up several times through out the night. I was originally prescribed half a 5 ml tablet but had no effect until I took 2 tablets (10mg). Because I didn't become suicidal immediately after taking the tablets I didn't realise this was what was causing it but after becoming sus I googled "can diazepam can suicidal thoughts" and sure enough there were plenty of similar complaints. I've stopped taking it and doing much better"
