What is it that is causing your depression? It is vital to know (but of course, I will respect your right to not disclose your situation if you feel it to be too personal/inappropriate etc) so we can offer
specificadvice.
I can empathise with you to some extent - I've been through short-term depression and it honestly feels like a black hole you can't escape.
So here is what I did to escape:
1. I talked to my relatives and my closest friends for support and told them about my situation. Obviously having the emotional support from relatives, friends and etc will help but depression is only something you can really overcome yourself. If you feel you can't do this and want to reach for a more anonymous approach like you've done, perhaps give Kids Helpline a call/email/chat.
2. I took a step back from life. This was done simply by going to say a beach and going for a swim in order to take things into perspective and realise that this is only a dark patch. A friend on this forum told me something nerdy haha that life is like a sinusoidal curve - When ever you're at the trough, you'll eventually recover to a peak
This can be done in other ways such as meditating which I found really helped me.
3. I changed my mentality. Mentality is everything. Try to be optimistic and grateful for the things/people you are endeared with. Too often do we take these things for granted and are left wanting things we don't want when we should be content with what most of us already have.
4. I took up a hobby where I could release stress in the form of exercise and thus brood less on the issue. Exercising is a very healthy way of releasing angst and helping you remain sane. I recently returned to soccer which really boosted my confidence and thus aided in feeling more optimistic.
It takes time Snivy, but eventually you'll overcome depression. You'll become a much stronger person WHEN you overcome it - it all boils down to your coping mechanisms and the way you think of life. Take the first step and put an end to it.
If you ever feel like you want to vent about current issues, shoot me a private message and I'll be glad to offer some advice that may/may not be useful to you.
Best of luck to you
