Some sort of depression or flatline?

Hey fapstronauts. Since April I have been feeling like something is missing in my life. It is like there is a hole inside of me. I am still happy when around my friends and such but it's not like I can be around them forever. It also seems like I have lost some benefits, im pretty sure once I go through this they will come back. Luckily I still have that energy and extra focus. I have gotten less erections then usual, but if I had to have sex or something it would get up. I don't plan on relapsing or "making sure my dick still works" because I know it works. Im not sure if this counts as a flatline. Can anyone help? Has any of you experience this on their journey?
