Hello Ripley, and a warm welcome to the site and understand that some comments can be more serious than others, but anyone who comes here to either post a comment or just read what other people have to say is a person crying out for help, so your comment is very important and will be addressed as such and by no means are you wasting our time.
People who take any medication for any type of depression, and anxiety is included in this, doesn't mean that everything is going to be OK all of the time, it's virtually impossible because we have to face different situations some of which we have not been prepared for, so it can affect our mood, that's understandable, and you must realise that because you take them doesn't make you infallible.
Sometimes when people feel emotional pain they transfer this feeling into physical pain and if asked why they can't answer that because it temporarily makes you feel better, but just for a short time.
You can contact Kids Helpline 1800 55 1800 either by phone, webchat or online by trained counsellors, but more importantly, we'd like to hear back from you.
Your story is of great concern to us and please take care.
Geoff.
