Can't seem to handle anything lately

I don't know what the hell is wrong with me but it is really starting to get to me.  I have been rediagnosed and so now I have a bunch of more shit wrong with me.  Lovely.  I now have Bipolar Type II, Major Depression, Generalized Anxiety Disorder with Panic and Agoraphobia, Post Traumatic Stress Disorder, and I have a Heart Rhythm Disorder with Enlarged Ventricles.  I also have Hypothyroidsim.  Thanks to all the abuse I have taken throughout my life, I also have been diagnosed with Scoliosis and Lumbar Hyperlordosis.  So, my head is fucked, my heart is fucked, my thyroid is fucked, and my back is fucked.  Great...what next? 
I constantly have stupid nightmares about everything that has gone wrong in my life.  I dream about my stepdad or exhusband beating me or raping me.  I dream that my kids are gonna get taken away (thanks Mom) and I just found out that everything I thought I knew about my family was just a lie.  My mother is a crackhead whore, one sister is a crackhead, one sister is a guilt-ridden Mary fucking Poppins, and my other sister has been treated like shit all of her life like me.  My family is so fucked up I swear!  I don't fucking know what to believe anymore and what to expect. 
I am on probation for at least another 7-8 years because my greedy bitch of a mom stole my oldest child, got grandparent's custody and sued me for back childsupport.  Now I am in debt over $16k because of her money hungry ass.  I just want my son.  But, she won't let me talk to him even though the judge says she has to.  I can't afford a lawyer so what the fuck can I do about it?  All I can do is try to pull myself together for the rest of my children.  They need a mom.  I just have to figure out how to fix myself first......
