I really like your question because I'm in a situation where if I lose my job (I'm still in (NZ's) 90 day trial period) I'll be back home and this is likely to very quickly leave my mind with nothing much to occupy it, which leaves me WIDE open to depression and general blah.
I have come up with a sort of plan if this does eventuate and I wonder if this might be useful for you too?
I'm going to take a full inventory of my life. What bits do I feel ok about, what bits would I love to add to, develop?
Then I'm going to ask: what would make me feel good to achieve/be doing?
When I lack ideas, it helps me to imagine what sort of things an imaginary person I admire would do with their time and life - what they might be involved in, enjoy doing - then kind of copy those things and integrate them into my own life.. lol well Happy, I don't know yet whether this starting point would be helpful or add anything to either you or I!
I was a SAHM for 14yrs or so, and one thing I quite enjoyed doing was decluttering and rearranging (I hate cleaning because it's continuous, but one-off 'big bang' sessions I enjoyed) until one day, I didn't. I just hit the wall and knew I needed to do something outside the home, it had become my prison rather than my refuge.
I imagine I'm return to study in the short term if I lose my job, just to save me from that sinking feeling I can imagine I'd get staring at the same four walls each day.
I'd love to know how you're getting on xxxmollyn
