There are many other forms of OCD. Not all are about routine actions. Some are about a sense of order. Some are about being supersticious. And then there is more. My understanding is that what is linked to them all however is a sense of forboding or catasrophic thiking if something isn't performed or placed as the mind sees as 'correct'.

Do you feel something bad may happen if you fail to do these actions?

I don't discount your depression. What I wonder though is what is triggering the happier thoughts and upswings? What suddenly makes you feel good? What if you were to use 'association' to remain grounded?
