As someone who has been to the rock bottom, I think the best advice is not to try to return to life the way it was before it went downhill. People have a tendency to assume when things are not going well, that it is a time to wallow in their emotions and regret that they cannot return to the past. The thing is, when you are already at the bottom, you have nothing left to lose. The bottom is not a closed box. It is an opportunity to start over and reconsider your wants and needs. The bottom is a chance to change anything and everything you want, as long as you believe in yourself and take action. The bottom is a time to forgive yourself and others for any events that you feel lead downhill. Never let the bottom keep you, for it was meant to inspire fresh foundations.
