I still say that you have a TM problem, but I wanted to just touch on another minor point that was discussed by someone above.
Let's just say that you had registered another non-TM domain in .net form and the .com form was already a developed site. This does not spell death either.
As long as the .com is not TM, a developed dot.com site can be a very good indicator of the good value of a domain name.
For example, Lets say you wanted to register xxx.us (just making this example up). You look at xxx.com, xxx.net, xxx.org, xxx.biz, xxx.info, xxx.co.uk and they are all developed sites, look good plus professional, and are run by companies. This is a pretty good indicator that someone else will eventually want xxx.us because the xxx is in high demand.
But again, in your case, the TM issue kills "MyPharmacy.net"
