thank you for sharing, it is good to hear about what you are going thru, it halps us kow what is going on with you.
I am sorry you are having a rough time.
The gardening can be as simple or complicted that you want. Depending upon where you live, an apartment with a patio, and what your light source is filtered or direct sun You could grow container plants jsut about anything in a pot. So you could start very simply.
Geraniums are good heat tolerant plants I know that my mother had one that she would bring inside during the winter and leave outside during the summer. We leave ours out year round andd they do well in direct sun. When you go to lowes or home depot the containers will tell you what kind of sun they will need, there will be a insert with writing instructions on it for care. Annuals only last thru the season, perinials come back year after year. mirical grow has potting soil with fertilizer in it already.
I have many potted plants on my patio but we rarely get temperaturs that are freezing so we get by with all kinds of plants, like I have begonias that last year round although they are an annual!
It is good that you are trying to start a hobby, it is fun wantching things grow, remember plants want to live.
As far as your job satisfaction. life is full of changes.
and with any job there will be aspects of the job that you won't like...I know that sounds pesimistic. I think that is just reality.
Maybe you could talk with some counselor at a local techical school about going to learn something in the medical field like radiology. What you are doing now is important work, don't minimise the importance of your work, peoples lives are at stake.
hang in there
