homestart might be worth seeing if these people work in your area. A friend of mine went through a bad patch and they provided her with much needed support.
Otherwise the children centres in area might have some outreach support or a two year old nursery place - what they offer varies wildly but might be worth an approach.
We had rough times when the DC were little and found when were were stressed - house moves, money trouble, serious illness - our toddlers did play up more just when we had least coping capacity. My mum kept telling me that young children are like weather veins - they pick up your stress and anxiety pointing it out for all to see -and don't know how to deal with it all.
I have children you tantrum a lot - one started much earlier than considered normal and continued much later - she is a very definite independent person - recent visit to secondary school she surprised one teacher with her very definite opinions about subjects she was interested in. She is a polite girl with lots of self confidence.
While trying to empathise with tantrums toddler is a good strategy on occasions - not all tantrums have sensible causes. Worst one I had to deal with luckily at home - child wasn't tried, hungry or sick had attention and toys but flew of handle very violently with me because I'd change their nappy which they'd wanted but thrown away their poo. No explanation or diversion would suit him I'd done him wrong and he was going to continue till I returned his poo.
I'm a bit
about all the posters who think if you walk away that the only technique you every use - not like you have wits to asses the situation and how to handle it. I wouldn't ignore a prolonged noise making tantrum in a library, walk of next to a busy road and have walked out in shops, cafe and restaurant with child under my arm.
Op judged it a safe place and a technique worth trying. I've had people interfere once in a deserted park and once in a empty shopping mall - wasn't far from the child at all but they knew better or didn't like to see upset children - children weren't actually upset it was all temper - the children didn't want a bar of them and it made the situation much more prolonged.
