I'm concerned about you, rainbow. I've had years of abusing drugs and know only too well how addiction can creep up on you. Before you know it, you're in a bad, dark place.
I'm not actually sure you want to change. At the moment you are holding things together; your daughter is not particularly affected, your finances are ok, you're managing to conceal your addiction in real life. You won't stay on that even keel, your life will start imploding if you don't stop.
Take the advice given to you here. Delete all numbers on your phone of anyone associated with your habit. Do not socialise with cocaine users. At this early stage you need to remove every temptation. Stop drinking alcohol until you are a long time clean, it will ruin your resolve. Remove all paraphernalia associated with using from your home; whatever you cut up with, the mirror etc.
You need to be prepared for the fight of your life with this. The intense high/ euphoria will be replaced by depression, panic and anxiety and severe cravings. It's going to take a lot to battle that on your own. I strongly advise contacting a NA group near you. As the name suggests, it's anonymous, there is no danger of your daughter being taken away or your family finding out.
You are putting yourself at risk of stroke, heart problems, seizures, liver damage. Long term use causes infertility. The blood or tissue you might see coming from your nose is the lining rotting away. Eventually your nose will collapse and it's not pretty. You also risk long term mental health problems. Paranoia, anxiety and depression are common after using long term.
I'm being harsh but you seem to be at a crossroads. It either sink or swim. Please seek help if you can't do this on your own. Picking up the phone to speak to the Samaritans when you are experiencing intense craving may help.
A drug addict doesn't have to be a pale spotty down and out wearing a dirty hoody. You're an addict and you need help.
Adopt a mantra and repeat it, remember why you need to stop. Concentrate on today; today you won't use.
Wishing you strength
