It is not a good idea to diagnose yourself. If you think you might be depressed, seek immediate help and a certified psychologist is the best answer. A psychologist can assess whether you are depressed or just under a lot of stress and feeling sad. Another option is medication. There are many antidepressant medications available now but some will cause side effects. Thus, a strict scrutinise from medical experts before consuming is important to avoid any health hazard. Depression is treatable, if you choose to. Instead of worrying whether you are depressed. Do something about it. And yes, right now and right on, even if you do not feel like.
