Welcome to the forum! You're in the right place to get support and advice 🙂
I'm sorry to hear you've lived with depression for so long. A number of others on this site have also experienced long-term depression. I've had OCD (an anxiety condition) for almost a decade now. I was diagnosed when I was 13. Do you regularly see your GP about your depression, or have you in the past? Also, have you tried seeing counsellors or psychologists? There's a good chance you have, but perhaps you didn't feel that you found the right professional - someone you can relate to. If you would like to see someone new about your depression, there is a directory on this site for accessing professional services in each Australian state. Go to the first option in the top blue menu (Get Support) and select Find a professional.
Having social support is vital for anyone, and especially for those with a mental illness. Try to spend time with family and friends as much as you are able to. I know that I would not be as happy and healthy as I am now without my family, my best friend, and new friends I've met recently.
Hopefully other people with more experience of living with depression will give you some advice too 🙂
Welcome to Beyondblue! As SM said, these forums are a perfect place to talk anonymously and get advice on things that may be troubling you. Many people here have experienced mental health issues before and we are all willing to help each other where possible.
I'm sorry to hear that you have been suffering from depression for so long. I understand that it is very draining and even though it seems like it won't get better, it will. You have felt happy before and you will again soon! Have you tried talking to close friends or relatives or a counsellor about your thoughts? This could be very helpful knowing you have a great support network around you who are always willing to listen and can turn to when things get a little out of control. Counselling can also be really useful because the counsellor can help you in a different way than how your friends and family typically would and they will help guide you through the decisions you make on your road to recovery.
Take care and keep posting,
