Your Lord has made mercy incumbent on Himself.

If you are studying the deen and not realising your own ignorance then your ilm is not benefittng you. If it is only increasing you in arrogance then your intention is not sincere. Re-evaluate and start again
"I have discovered from my own experience that whenever someone increases in knowledge, they discover how much greater their ignorance is"
[The souls journey after death Ibnul-Qayyim Rahimahullah page 37]
“Oh Abu Dharr! Don’t look at the smallness of the sin but look at the One you disobeyed.”

I don't know who needs to hear this out but; please, please don't give up on your deen. It doesn't matter how many sins you have done or for how long, just come back. Start again, try again, pray again, cry, yearn, JUST DON'T GIVE UP.
