No sin is different from the other, the effects are the same, sin is sin. A person who lies is no diffrent from a person who kills.
I'm not saying this to discourage you but in fact to do the exact opposite. If sin is sin, that means God can and will forgive ALL and EVERY single sin we commit no matter how big or small.
All you have to do is as simple as ABC:
A-: ADMIT to God your a sinner and repent
B-: BELIEVE in Jesus as your Saviour and your Lord
C-: CONFESS your sins to Jesus.
Do this simple steps and you WILL be free from the bondage of the evil one.
God loves you more than you can imagine and he will ALLWAYS wipe away aal your iniquities no matter how impossible they sound. Jesus died to redeem your soul no matter how bitter and dark it is. Just believe in him and you will feel an overwhelming Joy!!!

“Come now, let us reason together, says the Lord: though your sins are like scarlet, they shall be as white as snow; though they are red like crimson, they shall become like wool"
-Isaiah 1:18
