When I started here, I was in that situation. I didn't feel I had any answers to anything.
And then I discovered... several ways to help.
Some things came from my family of origin, rather than my current situation - because that was experiences where I knew what the outcome was.
Other things were on the watercooler. Maybe helping solve someone else's pet problem or household emergency doesn't seem like much. But those of us who "live" on this site are under tremendous pressure, and often these little things can put us over the edge. A bit of friendly advice from someone who knows what it's like to live on the edge, can be invaluable.
And sometimes, all we can send is hugs and caring thoughts, and we all need those, too.
Keep reading. Keep posting what you can of your own situation. And then... you will find ways to help others, too.
