No Motivation After Release From Prison From CC

I have been out of prison for a little over 2 weeks. 
When I was in prison, I was looking forward to being released and starting afresh. Since I have been home I feel depressed and don't have any motivation. My partner keeps asking me what is wrong but I can't answer him because I don't know. 
I'm not sure what we both expected but it feels strange and I hope the sinking feeling goes away soon. I would like to hear from any ex prisoners who are or have felt the same because I am having a tough time right now and everything is a bit overwhelming.
