For Anxiety Been on this medication for about a year now and I'm positive it works for me. I was diagnosed with MS and had a lot of anxiety and depression. This drug helps me calm down and take a different approach to things.

For Anxiety I take lorazepam for social anxiety. It seems to help. I feel more relaxed and talkative when I take it. It also helps me with severe depression.

For Depression I'm taking 15mg for ~2 months the problem is that 15mg is not enough for depression and when I take 30MG I will have a lot of anxiety .So it is not bad in low dosage be aware of increased anxiety when you take it in 30MG or more. I'm thinking to take it in low dosage 15MG with another drugI will check with my PD.

For Depression Having been prescribed citalopram, sertraline and diazepam in the past, I was sceptical that this would work. It's very early days, but it does seem to have a very calming effect. Main downside is I am very sleepy so would advise taking it at bedtime.
