Speak with a personal injury lawyer. I think your statute of limitations has passed.

Get with a lawyer ASAP. Limitations has likely passed, but there are some unusual circumstances that can extend the time period. It's fact-specific, so sit down with a lawyer to discuss.
You could still file a claim under certain scenarios outlined below. It would all depend on when you were aware of the causal relationship between injuries and the molestation. It does appear you were only "recently" diagnosed, and so there could be an argument that you have three years from the diagnosis date to move forward. See below.
This is a complicated situation in that a sexual molestation case has its own unique statute of limitations. A statute of limitations sets a timeframe upon which a legal claim must be brought or if will be lost. Typically, this is three years on most civil causes of action (shorter for some, defamation, for instance). That clock doesn't start to run until such time as a reasonable person of common knowledge and experience would be on notice that a claim might exist. The fancy legal word is tolling.
This is the statute:
SECTION 15-3-555. Statute of limitations for action based on sexual abuse or incest. [SC ST SEC 15-3-555]
(A) An action to recover damages for injury to a person arising out of an act of sexual abuse or incest must be commenced *within six years after the person becomes twenty-one years of age* or within *three years from the time of discovery* by the person of the *injury* and the *causal relationship* between the injury and the sexual abuse or incest, whichever occurs later.
