pay off the last of my credit card debt

I’ve just paid my last card debt!!!! So now, main things to pay all my bills on time and to exclude new debts. I am strongly going to build positive credit history and want to ask my mum to be a co-signer. So I will get good credit card with good features therefore good points in my credit report. But I haven’t decided what card to choose. I am thinking about Amex blue cash or Discover Platinum. They are pretty good.

so many things that I cannot afford! It’s just getting at me and all this is because I cannot pay my debt… seems like I overestimated my ability to manage the high interest credit card I own. Now, I got to re-establish credit with sime other bank credit card,.. which one? and how get approved? a secured credit card is a good option they say but is it guaranteed approval credit card for me? oh.. i’m lost now…
