welcome - though it's not under the best of circumstances.
since you are here now and "talking" about it, sounds like it is time for you start on this issue.
let me tell you from personal experience - it's NEVER too late!
hope you'll find good info, support and encouragement from others who have been there - as i have.
see you around,
