Hi Jen,,,I just wanted to say.....Hope this comes out right.......
The "average" life expectancy is around 80?? So you have only experienced a small portion of what your life will be....It really CAN change for the better!! For myself, I started getting out of my depression after age 40 {don't worry, I'm a slow one}....

I all of a sudden felt good, I tell everyone I ran away from home at age 40 LOL....But it's the truth....I had a bad accident & it left me with many forever injuries, including a Brain injury, BUT...it turned out to be "ALL GOOD" ,,it changed my life for the better.

I know the last thing you probably feel like doing is helping someone...BUT, when you do this, it helps YOU to heal...People used to tell me I was so nice to help & I would say, "thank you, but it's really selfishness,, cause it makes ME feel better"! lol...it really does...
Just my silly, crazy input...lol..Maybe it will help you..I hope so
