Do you think that any particular event has caused you to feel a certain way? Do you feel sad at all? Feeling distant can definitely be a sign of depression. I'm no doctor, but I do know what it feels like to be depressed. Some days are sad, some are lost, some are just internally painful for too many undetermined reasons. Feels like nothing will get better, that it can't get better. It can though. And you've started off great by realizing something is wrong.
Counseling can be really beneficial in helping you sort through your emotions. Also, if you pray, that may help you too. I know it is very difficult, but try to challenge yourself to do one little thing a day. Maybe read a book or short article. Fold some clothes, make a meal. I understand those tasks may seem daunting or overwhelming, but when you have a sense of accomplishment, it can help fight some of the bad thoughts and feelings away.
Good luck, hope to hear more about you soon.
