Man, I took finasteride for 13+ years.. never had any issues...
I am off it for 4 months now.. didn't notice any changes either.. Well, I did notice some increased sensations in my orgasms.. but now it's back to normal..
My hair thinned after I quit finasteride, it was thicker before I started.. but hey, I was 25.. I am 38 now, I have no means to know if my hair would still be thick... :/

You might very well be suffering from stress.. Stress can and DOES affect the hormones levels..
I tell you what, I quit finasteride because I got scared after reading a lot of **** online.. Before that, I was a happy ignorant.. I am considering going back to it, but now I can't un-read what I read.. Even though I never had ONE issue with it. Never felt better than while I was on finasteride.. Hair loss was something I did NOT worried about, never..
Now, it's a constant worry in bogging me all the time.. "am I going to bald in like 1 year?", "was finasteride really keeping my hair or I got a ****ty up-regulation and I am balding BECAUSE of finasteride?", etc etc... I stressed so much, to the point I could not sleep for 4 days STRAIGHT. ZERO hours of sleep.. Of course I thought I was going through PFS..
What I did? Well, my wife helped me a lot, I can say... I put my sh1t together, calmed down.. Managed to get back to my normal routine (exercises, food, etc), and my sleep is just fine. Energy levels too.. I am still a bit depressed, for sure. As I am balding again, after freaking 15 years... My hair was absolute the same during this period.. now my hairline has receded a good 2cm at least, and my hair is much thinner in general..
So, chill out.. I know it's not easy. But try for a month, one day at a time. And let your body adjust itself. It will!
