Random Depression And Fear

[haai14]

In the past 1 year i get hits of anxiety, fear and everyithing feels so depressed negative and overwelming. But i dont get any accociated taught with it i just feel it. Also i get hits that last 3-4 days that i feel completly lost, for example if im in my house i dont feel that im in the house i cant feel anything,. if im listening to a song i can only hear 1 seconds of it then the next 3 im completly lost and aware of nothing and then i can again 1 second.  Is that purging or just my mind fking up. because on some days im completly normal i just dont understand why this is hitting me. its hard for me to explain its just weird.
