You don't need a safety pilot to go up in IMC, you need a PIC, which you can't be because you're not instrument current.

Agreed with Twin, find your last 6 approaches and hold (we'll say that any given day you probably intercepted and tracked radials). Whichever event happened least recently, thats your start point. 6 months from that date, you are current. After 6 months, you have the option of doing the approaches and hold in an FTD/SIM, grabbing a safety pilot to do simulated approaches, or grabbing a CFII and doing them in the soup.

After 12 months, you must to an IPC with a CFII.
