Hey there deauveyon. Im sorry to hear about your stuggle and want to let you know there are many people here that are willing to talk about anything.
Are you stressed about something in paticular? Is it just your kids, is it work or something eles?
It starts by finding whats really bothering you in life then follows by remeding that issue. There are so many different ways to walk, look and live that you gota keep searching for the way that fits you.
I understand its hard seeing a Dr. Because they are expensive..But theres alwasy places you can start....Like here

youve taken it upon yourself to reach out which is an awsome thing. If the struggle doesnt get better by trying to let it out though facets like here or say a group meeting it is wize to seek a Dr.
You could also try a book store and look though the mental health section? Or whatever section self help books might be in...They have done wonders for me. A book store would be good also to let your kids chill and read some children books while you picked your brain with something that might fit.
Keep it up and feel free to post about anything ^_^.
