Hello Chipmunk, and a warm welcome to the forums.
It's not easy when you feel like this to ask for help, as you may try and convince yourself that your problems are yours and from what other people have previously said they have been able to overcome it themselves, but each one of us is different as are the circumstances, so what you're struggling with could be in another form.
It's unsure whether of these conditions started the others, but know from myself that PND can begin the aggression of the others, or perhaps vice-versa, not that I'm qualified to say.
We are horrified when any of one of these conditions begins to control us and do feel empathy for the kid/s we're trying to raise, but somehow they learn to adjust, the most important part is that you have not brought on any undeserved burden onto someone else’s life, we want to help you.
If you are aged 25 or under then Kids Helpline 1800 55 1800 maybe able to help you by phone or online chat.
If you are able to contact your doctor and ask them about the mental health plan, this will entitle you to 10 Medicare paid sessions to visit a psych, and because you feel hesitate then write down what's troubling you now, in the past and in the future, then all you have to do is just pass this onto the psych, this will help when you're asked 'how can I help you'.
Please come back because there's much more to talk about from our own experience.
