For the past 12 months and greater I have been feeling quite... 'down'. Not in the sense that I am sad and want to cry, but rather that I am very neutral (maybe more on the sad side) at all times. For example, I don't hate my life, but I don't like it either, I kind of just see life as this wasted time which serves no true purpose. Also, I am not sad but not happy either, just this bored, useless feeling in between. I don't know if this has been affecting me mentally but lately I have been:

- Experiencing a large disinterest in all activities which I used to spend hours each day partaking in.
- Very self-critical and feeling very worthless.
- Experiencing a large fall in appetite.
- Very impatient with other people and have been easily angered.
- Experiencing some sleeping issues.

While these point to depression, I don't feel sad but rather just bored of life itself, so I don't really know. What do you think is my problem?
