You should speak to a financial consultant, one who is certified to offer professional advice. If you don't want to pay the small consulting fee, or you don't know how to find a good consultant, take advantage of companies like Charles Schwabb where investment planners will talk to you about your options in order to get you as a customer.

If you are wanting to close this $2k account, one option might be to roll it into a regular IRA first, recover the taxes you paid on the original $5K (you pay upfront taxes on Roth contributions), and then roll the regular IRA back into a Roth, now paying taxes just on the $2K that remains.

Again, talk to a professional who is certified to guide these decisions and who can fully understand your current life situation and the volatility of the market.
