Hi Vampy,
I've seen your posts ever since I've been on this site, and I always like reading what you have to say. So know that you have been noticed and I am truly sorry to hear that things have been so tough for you.
I could see why you are completely overwhelmed. Where to even begin? I believe no one can tackle everything that has gone wrong in their lives all at once. So I would say pick out what is most important to you first, deal with that before moving to the next. I can see that your child is most important to you, so what can you do to get custody? You probably have to have a place to live first. Homelessness to me is your first problem. I googled, "How to help homeless women?" There are so many organizations that can help you. So Google this.
Next money. Are you on disability or SSI? Are there govenment programs in your town that have social workers? They can direct you in so many areas.
Your emotional and medical problems -- are you on Medicare or Medicaid? How do you deal with health issues? There are meds for bipolar and anxiety issues. Are you on these?
Is your CF being taken care of? If you can't get treatment, you must find out about government programs. You may even have to move to a state that has free medical treatment for genetically handicapped persons. Many states offer excellent health care at major medical centers.
Are you estranged from family members? If you are homeless, I'll bet someone in this world would be very sad to hear about this and if you reconnected with them, would be happy to hear from you. If pride is stopping you from reaching out, try regardless. When you find it difficult to move forward, think about your child and the goal. Gather up your resources and push through it. If you have CF plus all these problems, you've survived against all odds because you ARE strong.
I always like to think of this metaphor. If you have a huge house and you are not up to cleaning it. Each day, you clean only one room. By the end of the week the whole house is tackled.
Think of the goal, and tackle only one problem at a time. Good luck. And when you feel lost, go back each time anad think that each small thing that you are doing will bring you closer to what you want the most --your child.
