What about her employer perks with insurance options? Talk to HR.
If not, she should at least speak with a broker to figure out some options.
Next, she can pay cash price at the Doc in a box locations for the times she is sick and needs meds.
She can look into a government program to see if she qualifies, at least temporarily.
Bottom line. Take responsibility for herself and man up even needed, even tho it us hard. Many Dr offices will accept a payment plan if someone at least shows initiative and responsibility. TOO many people expect something to be donated, etc due to their " circumstances". Take personal responsibility and feel better about yourself for having done so.
As far as catastrophic care... If you are without coverage, at least try not to do stupid things to cause stupid accidents which can be prevented.
Best wishes. It is hard starting out but it can be accomplished without relying on others. Do research and find the best plan for yourself .
