Hi I can relate to you a lot,I have two fab kids and husband who,to be honest are the only reason I'm alive.
I was a successful educational practitioner with lots of qualifications,perfect family and no money worries. Now I'm physically disabled and dependent,got no cash and so depressed.
My parents and family have no understanding of how I feel and nor do they care,only my husband knows the real me and I feel so guilty for the way I rely on him,so I sometimes say nothing.
I know exactly what your saying by being strong for the kids,I'm always worrying about the effects my disability has on them.
I'm currently seeing a psychiatrist who seems to think I have all the time in the world whilst he tries to diagnose me,he does not even attempt to treat my symptoms,even though I shouted at him to live with me for a week to see my mood swings lol.
I even ring helplines just to vent my frustration on someone who will listen without prejudice,maybe that could be an option?
Are you seeing someone? If not would you consider visiting your family doctor?
Remember our children need us but we also need someone too!
I'm always available if you need a chat.
Take care
Jk
