I just took a few depression tests?

If you took a random test online or in a magazine, those tests are not good so don't pay any attention to them. The only way to test for depression is through a counselor or psychologist. They do assessment tests called the Beck's depression inventory. Other tests just give out random information and are not reliable at all. It is very possible to still be depressed, and yes you will be able to get over it on your own. Most people are able to deal with depression on their own. It is important to tap into your personal strengths and find ways to feel good about yourself. Staying busy is also another good way to help. If you are still depressed in a couple of months, consider talking to someone who can help.
