Some parents they are to automatically assume that you're suicidal and send you to a psych ward.
Why don't you just talk to them about it, they might be able to help.
If you're suffering depression, don't psychiatrists help, even if you're not suicidal, which is pretty simple to explain once you get there?
Just find stress relieving activities.
Jack off. Get aggressive behavior and take it on an object.
These two actually work very well.
Relaxation helps you to feel better and put yourself in a state of mind where you can feel ready to go ahead and accomplish things, which in turn can make you feel better.
There's no point standing around and moping and crying to the internet.
Find a hobby or something to relax, and set yourself some things to focus on.
If things get too stressy, partake in your hobby, and continue to focus on what you want to do.
It's also a good idea to set your focus on education and work, so you can further excel yourself and improve how you feel. There's no doubt that people with stable jobs/relationships and good education will generally live better lives than those without. So, set yourself some long term, and even short term goals.
Just shake off the depression, even if it's with something as silly as playing a video game or touching yourself.
Then step by step focus yourself.
