I’m experiencing a really positive shift in my mood having been ill with severe depression for over 2.5 years and a previous breakdown about 5 years before that. I’m now at the point where I’m feeling ready and slightly excited about organising some voluntary work- 1 half day a week, gradually increasing.
I’d like that work to be at least partly related to finding a paying job in the future. But I’m really stuck as to what I want to do. Therefore, I welcome ideas from all and sundry. Police, military, anything requiring a security clearance and high stress jobs are all out (unfortunately).
Have a degree but was got over 10 years ago. Also not specifying what it was in so as to get a wider range of ideas. Mid 30s. Willing to train but can’t afford to go back to uni or grad school.
Skills/Like/wants: investigation, problem solving, some IT, advice giving, teaching/training small groups or individuals, not always stuck in an office, scope for part time working, don’t find public speaking stressful, ability to work little supervision. I have a driving licence.
Don’t want/not helpful for me: front line customer service, cash handling, sales targets, rubbish at anything crafty-models, wrapping presents etc
Hobbies: language learning (nothing fluent yet), art, swimming, travel (if I could), animals, gardening, cinema.
Wotcha advise? 
Some sort of non-profit might be a good path. You can typically volunteer and it may lead to salaried work.
Substitute teacher. It sounds like you qualify and you could start with a minimal number of work hours. In addition, it pays (which volunteer work won’t, obviously) and you would gain experience that will look decent on a resume.
When my daughters were growing up, I encouraged them to think outside the box and apply for non-traditional jobs. My oldest went to work in a mine warehouse and learned some really useful skills while being paid much better than working retail shops. Later, she quit and got a good job in town in an auto parts store. I’ve known other women who worked in industry, every thing from heavy-equipment operators to welders. They learned useful skills while earning top wages.
If you’re willing to spend a little money, I would suggest getting a psycho-vocational assessment done. I did and it has led me to become a researcher. I’ve never been happier!
How about working at your local food bank? You could start off as a volunteer and eventually get a paying job there. You wouldn’t necessarily have to meet the clients. You could spend your time stocking shelves, receiving donations, participating in PR functions or maybe doing the organization’s website or FB page. Some food banks have as a big part of their mission serving the needs of OTHER food banks in poorer or more rural areas so they have enough food to distribute. You could help out with that as well.
Just an idea to consider. A lot of other good ideas in the other posts. Good luck in your search. I know that recovering from depression is tough and at this point being able to find something steady and consistent, even if very part time, is the most important part. I’m glad you’re feeling better now.
Is there an “arts” theater around? These are in old, run-down theaters and have seats and sofas and screen obscure films for a limited audience.
They are always on shoestring budgets, and a free person to help clean up, re-stock the concession stand, run the popcorn machine…
A year or so you can go to a place that shows mega-busters - also not rich, but they can pay.
The animal shelter might not work out - seeing a freezer full of dead cats would be bad enough, but being asked to round up the “time expired” critters and putting them in the gas chamber might be too much.
Unfortunately, “money” and “no stress” are hard to find in the same place.
If you can stay awake all night in a quiet, dark room, Hospitals have use for people to watch certain people - sometimes it is a suicide watch, sometimes it is a risk of acute medical emergency. Your job is just to call the nurse on duty, and stand by at the nurse’s station. Whatever it is, they don’t want you in the room as it goes down.
Zoo’s can always use cheap labor, but I don’t see that leading to an income except at that zoo - it’s not like there are multiple zoos in the same area.
