It's not easy. Especially with a 4 year old, and a newborn.Damn sounds terrible I'm sorry buddy. Have you rethought going to a doctor and get some type of medication? I understand your hesitation because I hate taking meds also. Then again not sleeping is horrible too. Hang in there buddy.
In some ways, I wish I could take meds, but then I get even more anxiety knowing I'm taking something, so that won't work for me.
I just have to keep going through this, hopefully I can build up some confidence and some resources, and I might get to the other side of this as I did in 2014.
Funny, in 2014, I thought all of my struggles were because of the side effects and withdrawal effects of the meds. Now I realize most of this was just my own anxiety. Scary actually!
