Sharing Our Innermost Thoughts

I am in middle of my exams preparation. Before starting my preparation I had a breakup for the first time. But these exams are so important to me…so my ex (the person who broke up with me) has helped me to overcome from it…
I was so glad that he is helping…but what happened is I was so used to him during my preparation…
Actually he is also trying to give his best in these exams…But instead of focusing on his exams…he helped me to overcome my depression…so he was lagging in his preparation…
Now that I am alright…he wants to focus more on his studies…I am happy for it…
But yesterday I was so distracted and I called him for help…
He actually helped me…but later he burst and scold me that I am the reason for his lagging in studies… not these few months but from the beginning of meeting…because of me he suffered a lot…
From then I thought of not seeking help from him ever again…
But the things he told me were killing me from inside
I feel worst for myself for ruining his time…
And these thoughts are reminding me the reasons for my breakup…I cannot say the reason for breakup is only one person fault…Its just that we two people are quite opposite in everything…
I really had to remove these thoughts and concentrate on my upcoming exams…help me…
