Is it Worth Doing an Un-paid Internship at This Point?

The current situation is looking really bad as a lot of internships are being cancelled and I simply can't seem to find anything this summer. There are however a variety of un-paid internships related to the work I'm very interested in. Do you guys think it's worth going for these?

I don't know what else to do at this point, I just want to spend my summer learning and being productive. I need something that I can put on my resume which will help me get a good job for next Summer.

Please give me your opinions.

Thanks
