Eating haram food is indeed a grave sin. Consider the following hadith:
عَنْ أَبِي هُرَيْرَةَ، قَالَ: قَالَ رَسُولُ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ: " أَيُّهَا النَّاسُ، إِنَّ اللهَ طَيِّبٌ لَا يَقْبَلُ إِلَّا طَيِّبًا، وَإِنَّ اللهَ أَمَرَ الْمُؤْمِنِينَ بِمَا أَمَرَ بِهِ الْمُرْسَلِينَ، فَقَالَ: {يَا أَيُّهَا الرُّسُلُ كُلُوا مِنَ الطَّيِّبَاتِ وَاعْمَلُوا صَالِحًا، إِنِّي بِمَا تَعْمَلُونَ عَلِيمٌ} [المؤمنون: 51] وَقَالَ: {يَا أَيُّهَا الَّذِينَ آمَنُوا كُلُوا مِنْ طَيِّبَاتِ مَا رَزَقْنَاكُمْ} [البقرة: 172] ثُمَّ ذَكَرَ الرَّجُلَ يُطِيلُ السَّفَرَ أَشْعَثَ أَغْبَرَ، يَمُدُّ يَدَيْهِ إِلَى السَّمَاءِ، يَا رَبِّ، يَا رَبِّ، وَمَطْعَمُهُ حَرَامٌ، وَمَشْرَبُهُ حَرَامٌ، وَمَلْبَسُهُ حَرَامٌ، وَغُذِيَ بِالْحَرَامِ، فَأَنَّى يُسْتَجَابُ لِذَلِكَ؟
Abu Huraira reported Allah's Messenger (ﷺ) as saying: Oh people, Allah is Good and He therefore, accepts only that which is good. And Allah commanded the believers as He commanded the Messengers by saying:" O Messengers, eat of the good things, and do good deeds; verily I am aware of what you do" (xxiii. 51). And He said: ' 0 those who believe, eat of the good things that We gave you" (ii. 172) He then made a mention of a person who travels widely, his hair dishevelled and covered with dust. He lifts his hand towards the sky (and thus makes the supplication):" O Lord, O Lord," whereas his diet is unlawful, his drink is unlawful, and his clothes are unlawful and his nourishment is unlawful. How can then his supplication be accepted?[1] 
However, now that you have recognised the severity of your actions and the magnitude of its implications, the only thing you must do now is make sincere repentance to Allah Ta’aalaa. Allah’s mercy is ever vast. Allah Ta’aalaa mentions in the Quran:
قُلۡ يَـٰعِبَادِىَ ٱلَّذِينَ أَسۡرَفُواْ عَلَىٰٓ أَنفُسِهِمۡ لَا تَقۡنَطُواْ مِن رَّحۡمَةِ ٱللَّهِ‌ۚ إِنَّ ٱللَّهَ يَغۡفِرُ ٱلذُّنُوبَ جَمِيعًا‌ۚ إِنَّهُ ۥ هُوَ ٱلۡغَفُورُ ٱلرَّحِيمُ ( ٥٣ )
Say: O My slaves who have been prodigal to their own hurt! Despair not of the mercy of Allah, Who forgiveth all sins. Lo! He is the Forgiving, the Merciful. (53) Surah al-Zumar
Inshallah, by making sincere repentance, the sin of eating haram will be forgiven. In the future, exercise extreme cautious with regards to what you consume.  
And Allah Ta’āla Knows Best
