GettingWellAgain

This is probably stupid to ask this, since I KNOW I have OCD about mental health and have been diagnosed with anxiety, OCD, and depression, but I need reassurance and am going to ask anyway. Okay, I take Trazodone for depression and anxiety and I have not taken it for two weeks due to an inner ear disorder I have, as it increases my dizziness. I noticed that I became progressively more depressed since going down on the dose and then not taking it, and for the past few days, I have been pretty moderately depressed, have not wanted to get out of bed, and have not wanted to do anything/talk to anyone. Today was especially horrible. Right now, I'm in a good mood though, and it makes no sense to me. I keep thinking, "Why am I in a good mood? I'm DEPRESSED. I'm not SUPPOSED to be in a good mood." That, I know, is my OCD speaking, but the intelligent, suspicious side of me tells me that I have a right to be worried because depressed people don't just suddenly get in a good mood. I have been chatting on the computer the entire night with a pleasant person, but still, it makes no sense to me. I keep telling myself that there aren't any RULES to being depressed, but can one be depressed most of the day, and then suddenly feel a little bit better or is this considered rapid cycling? Thanks for calming my anxious mind
