So, I have blocked him everywhere. Ceased all contact with him. But my reward pathway is gone. I am kind of having low mood, no motivation, sleeping for hours altogether, kind of feels like I have lost it, that too in the one month of knowing him. WTF is happening to me. Was he that important to me? please suggest how to get over this.

Edit: for some reason I am not able to reply to the comments section. I have been trying for the last 2 days, ugh! Anyways, thaaaaank you fellow HVWs for your valuable suggestions! Ahh, I will include regular walks into my routine, and yes, I realised I had fantasised my ideal future with him, so when it went for a toss, I lost my ground. But I will keep it rooted this time.
