Its ALL hills near where I live and most spots are too steep .- any tips on slowing down and pushing?

I actually abandon the skateboard when I'm gonna fall bc i cant seem to accept defeat </3 two days ago i fell for the first time (I go the board 17 days ago and use pretty frequently, cruising to te gym, and a little bit of trick practice but its mostly just cruising) there is a few spots by my house that are good but its RIGHT by the road so i have to be supervised. TBH my parents wouldnt take me very far just to go skating and I cant drive or rlly go with other skaters so im probably just gonna stay near my house where its hilly. I get ahead of myself and trip over my own feet when pushing and almost jump off the board when I'm falling and I cant seem to slow down correctly or I trip. Any tips in general?
