ADs are a tool, not a crutch. It is up to you and a counselor to decide if you would benefit from them. You are right in that this is a situational depression, which also means that you would not be on the meds forever. I used them for about 2 years, and they saved my life. If you broke your arm in a fall, would you just let it heal "naturally," or would you go get a cast?
Please see another lawyer - try to ask around for referrals (do you have a local women's center?)
