Taking $30m that will wipe out most of your stake, and still not carry the business through to profitability seems like a tough road to go down. You've said you're not sure you have the energy, and I expect that your energy will go down even further with a much lower ownership stake.
If that's the case then I would be looking for any option to not do that which seems to be either selling asap or cutting your burn rate drastically. You have 6 months of runway. Can you cut your burn rate to 0, or 2/3 or something that will give you a meaningful runway without raising the additional $30m?
It may also be a case of walking away. You own a good chunk of the business and if you think the board is going to fire you anyway, perhaps it's better to let someone else take the CEO job, you keep your stake and do something else?
