I'm going to guess that you are a pretty awesome friend :)
I imagine you go that extra mile, give that extra something - whatever it is that they need at any given time.
When they are sad, you are there with a shoulder to lean on.
When they are tired or stressed out, you suggest (insist?!) that they take some time for themselves.
You let them know that it's okay to sleep in, take the day off, watch some mindless tv, ask for help. To not feel guilty about it.
When they start to beat themselves up, you encourage them by reminding them of all the good that they are. What they have accomplished, how far they have come, all the wonderful things that they do.
You send little texts of loving care, drop off soup, run an errand for them, send a funny meme to help them smile, let them rant and rave, share their frustrations, invite them over at any hour.....help in anyway you can.
You would pretty much drop everything to lend a supportive hand in their time of need.
You would help them realize that everything is going to be okay.
I bet you would even step out of your comfort zone to help.
For example, I am pretty lazy when it comes to anything 'labour-ish'. I am a big procrastinator and lover of sitting with a coffee and a book. Not much of a doer over here!
However, if a friend needs me to put together IKEA furniture, or pick up/move/drop off anything....I WILL SHOW UP.
I will put that coffee in a travel mug, stick a bookmark in that book and be there!
You are the same. I know it. You would undo your usual way in order to be there.
TO SHOW UP.
BECAUSE YOU ARE A KIND, COMPASSIONATE, GIVING SOUL!
And that feels good.
