Find the strength to get over it
There are many emotional hurdles which we as humans can hit during our long journey through life. While probably the hardest thing to get over is the death of a loved one, the next hardest thing to get through with is life after having a divorce. It can create quite an emotional shock, especially on the person who didn't think it was all that bad. The longer a couple has lived together, the harder it becomes to endure a divorce, as the routine happiness which came from always being in the company of someone you love and who loves you in return is instead replaced by the old single routine. And that is why most people have a very hard time overcoming their post-divorce problems; they exile themselves from the various social circles to which they belong and even from their relatives sometimes. While some people will claim it will be for the best to take this route, the truth is that in a grand majority of cases this only leads to the development of a greater depression, which will eventually send the victim on a downwards spiral.
Instead of seeking comfort and help within yourself, you should maybe try and look for it outside. If you have a family member that you've always had very tight and good relations with, be it your father or your cousin, then without a doubt you should try and spend some time with them. Spending some time with a person who genuinely cares about you and loves you as a person can be quite heart-warming and remind you that not everything is as bad as it seems.
If you haven't had the best of relations with your family member or simply would prefer to keep them out of your emotional life, then what you need to do is turn to your closest friend. Organize some parties with them, go out, enjoy life and simply have fun among the people who have always supported and been there for you; some people would even go as far as calling their group of friends a second family, a second home.
However, if most people with depression simply had to have a talk with their family members of friends then it wouldn't be such a problem. In many cases the depressive state stems deeply from within, and instead of the company and help of friends you should maybe seek the guidance of some type of counselor or psychotherapist. What you basically need to do is find a new way in your life; find a new calling. This may actually be the perfect time to look at yourself, analyze your thoughts and emotions and basically get to know what you are like.
All in all divorce can be a very tough event to get over, so don't go through the torment by yourself. In time such as these you must reach out to your friends, family members, and any other resources available to you to help you get past this black spot in your life.
