In the former case–a situation with which I’m familiar, and it’s sadly all too common–it’s that girl’s responsibility, once she’s of age and if she wants to change her life, to get the skills she’ll need to survive as an adult. You don’t need computer skills to work in fast food, or in most areas of retail, for example, and those few that you need (searching inventory via a software program, for example) are usually so specific that they’re learned on the job. Again, I am not saying that these are easy decisions to make! However, they are necessary ones if she’s going to become a functioning adult. This is one of the biggest issues I have with a lot of the homeschooling movement, but that’s a rant for another day.
In my case, I had a bare minimum of computer skills (read: I knew how to use a mouse and keyboard and could two-finger type), and absolutely no social skills because I wasn’t really allowed to socialize with anyone my age lest I be exposed to “bad influences.” The few people I was allowed to socialize with were almost all even more sheltered than I was. Another thing I had to realize once I decided to leave home was that I had to learn social skills. Honestly, I think learning social skills was harder than all the work I put in at school and in jobs. It really was like learning a whole new language, but one in which not just words and inflections, but body language and facial expressions “spoke,” too! What helped me was looking at people around me who seemed at ease in the world and with people, and imitating what I liked about how they interacted. I’m still not entirely at ease with all social situations, though that’s partly because I’m extremely introverted, but I’m sufficiently good that I worked in customer service my entire working life and was quite good at it, judging by the reviews and raises I got.
I didn’t know how to go about getting a job, but I knew that there would be one out there for me if I looked long enough. I started by going to a street in my city with a lot of retail stores and restaurants, and walked into every single one with a resume (had to Google how to write a resume) and dressed as though I was going to an interview. I’d ask to speak with a manager, introduce myself, ask if they were hiring, and then fill out an application. I was very bad at this to begin with, but gradually improved as I did it over and over and over again. Practice makes perfect. I submitted over thirty applications before I got my first retail job.
You do have an excellent point regarding the mental health or other medication aspects. I’d think that a person who requires medication could apply for Medicaid and get most of their medication costs covered by it due to being so low-income, but I’m insufficiently familiar with that scenario to say for certain if that’s feasible. As far as the physically disabled, I have no solution for that, and that’s another point which I hadn’t considered. I was blessed with very good physical health, and rarely had to see a doctor. I suffered from depression, but I didn’t have to go on medication for it as I found that between Al-Anon meetings, working a program, and staying busy with work and school, I just didn’t have time to get as depressed as I otherwise might have. Someone with bipolar, or who needs help to do basic life activities, would be in another situation.
