"if I had a tesla battery that worked in my flashlight"
That would have cost you $32 and change and Tesla would have reported a loss of $19.75 for every battery sold.
That happens four times a year. The next one will probably be the second week of August.
In the past six months it has traded (very roughly) in the $7.50 to $9.50 range. During that time you could make money with calls when the stock hits $8 and puts when it goes over $9. In the long term the company is toast.
You choice is to realize the loss, take a deduction against any gains you have now or going forward, and to put what money you have left into something that might grow. Otherwise you'll just lose the rest of it.
