Just that really.
I used to be a teacher, loved it.
Had ds, went part time, didn't love the job so much.
Had dd, really really didn't love it anymore.
We relocated for dh's job a few years ago and I became a sahm. I didn't miss teaching at all and decided I wasn't going back.
Fast forward a few years and the dcs are both settled in school. And I am at a bit of a loss what to do with myself. 
I have hobbies, I am currently working my way around the house on a one-woman DIY mission. I'm busy and doing productive stuff. But I feel like I've slightly lost my purpose in life. 
I'm guessing that's normal when a sahm's dc are both at school. But it doesn't feel great.
I'm also not that long off a course of ADs so I don't want to slide down that dark hole again.
I've vaguely started looking for work, but I have no idea where to start as I won't be teaching again.
Anyone feeling the same and want to wallow together or does anyone have any tips to get myself sorted?
