I have experienced most of what you're describing, sudden suicidal thoughts, low motivation, difficulty following through on tasks - and it's good that you recognize that you need some support to get through this. The forum has been great for me in this way.

Regardless of when you next see your therapist, I think it's very important that you go and see your physician asap and discuss some of your symptoms with him. I was on a very low dose med for 2 years and it was working wonders, but then it just wasn't anymore and I needed a higher dosage. I think it's worth discussing with him/her.

Also, are there any depression support groups in your town or one nearby? I joined one recently and it has been a really great way to connect with people and talk openly about my feelings in a non-judgemental atmosphere.

Hugs to you,
