I have recently been sent back home from university due to being in an extremely depressive sate. It is best to begin back when I returned to university after Christmas. For the first day or two I was fine. After I went into a highly anxious and self-loathing sate that had daily up and down periods. Though it was mostly down I had moments where my mental state was fine and confident. This continued for a bit over a week.

This ended when I had to return home for a few days were my mental state changed to being more confident. However, this changed again when I went back first I was felling supremely confident for a few hours. My mental state then again changed to feeling extremely depressed and not wanting to do anything at all and wanting to go home.

At this point I went to the university's mental health team and at the time linked my current mental state and the one I had been in before I went home together and said I was felling homesick and depressed. After this my mood picked back up again and I felt in a reasonably normal mood. The depressive mood though returned the next day and the university mental health team set me home for the weekend.

Over the weekend the depressive mood continued. I spend the weekend barely talking and interacting with people and mental regressed in age and being slightly clingy.

I had still at this time attributed all of this with homesickness and ignored the anomalies. However, events today have made me reconsider this. Today I started of the day as I had previously feeling extremely depressed. By the evening thought this had worn off and my mood had gone to being anxious and worried about my future and what was going to happen and coming up with unrealistic bad scenarios. This mood though quickly wore off in a few hours. Now I am feeling confident and energetic.

Sorry for the wall of text. As the post title says can anyone tell me what is going on or really if it is what I think it is. Also, another thing of note in each of these different moods I find it hard to remember what it felt like in the other moods and my memory of it feels distant and disconnected.
