Depression. Now in a huge guilt.

A year before i met a boy on fb, we just had a chat since i was bored and single for long duration i met him, and we had sex. He was clear that its only one day story but somehow i developed feelings for him. I begged him to meet me more. We met for 3 to 4times during last year. This year i am preparing for neet pg. Only 6months are left any i am in very much panic. I was not in contact with that boy for 3months. I wanted him to talk to me. As he was not interested to talk, just a thought came to my mind that i should prank him that i am pregnant. I lied to him generated fake reports (as the boy lives far away from me he lives in mumbai nd i am from indore). To prove my lie, i lied to him many times. For ex: i said i took abortion pill now my stomach aches. Till this point everything was normal but i was indulged so much that to prove my self right i created a mini abortion i went to washroom with help of paint colour & slime created a 12w abortus. Now in a huge guilt.
