When I first registered here (I was dx'd with depression, and about to be dx'd with bipolar at that stage) I was 145. I was battling with depression.

Now I took the test earlier on today, and I'm a 95 (Mania from Bipolar is coming through!)
129 would indicate that it is a good idea to go and see a mental health professional if you aren't already. A therapist (T) would be a good starting point, or a school counsellor - if you're still in school.

An online test cannot be 100% accurate and just gives some guidelines which you can then further explore with a professional.

In the mean-time : Hello and welcome. If there are any questions, feel free to drop me a PM, or have a look at the various forums here
