I wouldn't beat yourself up too much about buying in today. How about the investors who put up 80m in the cap raising 5 months ago ... 75% of that investment is gone (so far).
Even if you value their assets at zero the cash in the bank should be worth 5c a share, although who knows how much of that is being burned each month.
The large volume selling today looks like panic, and so the freefall continues.
