i need prayers

ever since my dad passed last month i have been smoking weed everyday in abundance and drinking every chance i can to not be sober. i went to church on sunday and had a chance to think about my actions. i dont want to rely on drugs and alcphol any longer. idk if its withdrawl but im feeling really depressed trying to deal with reality. my house is a mess and i have two kids under the age of 2. i NEVER put them in harms way so plzzzz DONT. but i need some encouragement to move forward
