That super sucks! Sorry to hear you've been having troubles...
I've only been camming for 8 months only but I can tell you that I started off really strong on CB, then had a really bad period, to now back to being successful, or successful for me, at least (right now I get on an average day 600 people in my room and on an amazing day I've had 3000... still don't know how that happened LOL) so maybe I can offer some help.
I started camming when I lived in the states and then moved after 1 month to a new country with a totally different time zone... so ALL of the fans I gained in my time in the states were basically pointless because they couldn't attend my shows anymore. I was doing shows at 8pm EST in the states and then had to start doing shows at 1pm EST because of the time difference... the 8pmers weren't also 1pmers. I went from having a lucrative, great beginning, to like 15 people in my room. What I did was keep trekking on to be honest. I kept going and going and I don't know what exactly happened (I think it was just a really sexy show) but one day my room count skyrocketed. I couldn't believe it. Maybe what you can do is just keep going and stick to a pretty good schedule, build a twitter if you don't have one, etc. and treat it like a beginning again.
It also definitely didn't take me 4 days to bounce back from that bad spell, maybe a few weeks to a month, even. But if its something you really want, I'd give it a month and then reevaluate again. And try to keep as calm as you can. I was literally having stomach issues from the stress of not doing well on cam, but it definitely doesn't help.
Also- there was a point where I made a new user name maybe a few months ago, and I somehow got a NEW tag. CB told me that I wouldn't but I did (maybe it was a mistake)? So maybe a little brand refresh and new username could help. CB will transfer all of your followers to the new username. They might've fixed the bug that gave me the NEW tag, though.
Again not an expert by any means but I know the feeling and it can be so disheartening. I guess I just tried as hard as I could to keep a smile on my face. Another thing I noticed is that when I went from camming for 3 hours to more like 5 hours, I was much much more successful.
Good luck! Keep us updated.
