I was diagnosed with depression a long while back. I stopped taking the medicine because I hated how it made me feel (and it never really worked). I ended up being able to get Pharma Grade IV/IM Ketamine and that pretty much CURED my depression. Thats right CURED. Took 25mg twice a week for about 5 weeks (intramuscularly) and depression is all gone. The good thing about Ketamine is that it works FAST, instead of having to wait for weeks or months for the medicine actually work and reach a stable level. I felt much better just after the first use.
Doctors are giving this drug for depression now, and it works extremely well. But its extremely expensive. Typically an IV is started and its given over an hour or so (in a controlled setting). Im not sure if they give it to pediatrics, but its definitely worth looking into. It works.
As another user said, personal space was really big for me. It allowed me to do things that I wanted to do. I just wanted to play video games and browse the internet without interruption and that made me feel better. Note, this was back in middle school (about 13-14 years ago). What does your daughter like to do for fun?
From experience (because of my job), if people spontaneously start to get better and you notice a change in her personality that's not normal for her, drugs
might be being used. Children are great at hiding things, and you'll never even know. Drugs release dopamine and endorphins that can help with depression, and you can notice changes almost instantly. Just a heads up, just in case.
**Talk to your daughters MD about ketamine! A LOT of people (especially parents) would automatically just think "No, thats a bad drug!". But I cant stress enough about how great it works. It literally changed my life.
