I am not sure where to post this, but i thought here may be best. I am finding if really hard to explain what has happened to me, especially to my doctor and therapist.

Its almost like I’m not getting the same hormonal regulation i used to get.

-i don’t get that feel good chemical hit that I used to get around food, gaming, exercise, sex e.c.t.
-it feels like everything internally has been dampened slightly 
- i used to feel really alert/ energetic, felt my heartbeat loudly, blood pressure after eating, muscle tension, now I don’t feel that anymore 
-i feel anxious but I don’t get the physical symptoms of anxiety

As i said its difficult to explain but I’m wondering if anyone experienced anything similar? its been going on for nearly a year now, it happened after a heavy night drinking. 

I guess this is just how i am now but i really miss how i used to be and I’m confused why this has happened
