I would be careful with this. When I get depressed, I often withdraw and it seldom helps, as now I have lost connection with the outside world which can help to draw me out of my unhealthy perspective. If the forum provides you with an outlet and you feel safe here, I see no reason to take a break from it, but there is also nothing wrong with taking some time to be away from the world if that is what you need to regroup, so long as you are taking the time to actively nurture yourself by eating well, getting outside, keeping your mind busy, etc.
It's also important to not be hard on yourself. Depression happens and it happens to far more people than those who would admit to it. There's nothing shameful about it, and if it has reached a point that this state just feels like it won't go away and if you feel a loss of control, asking for help/advice from mental health professionals, friends, family or people on the forum is very healthy.
Some of the most basic things can be immensely powerful, like drinking water, eating good food, breathing mindfully, watching silly videos. Treat yourself like a good parent would treat their sick child, and do what you need to for yourself to get through this.
