Hi, I'd appreciate any advice you can give me. There was a girl who I went to school with, for simplicity's sake we can refer to her as L.

I went to the same school as her for 2 years and for over the first year and a half, I never particularly noticed or paid much attention to her (she was the year below me, but our 2 year groups shared a common area so I saw a lot of her, and there was only a couple of hundred people in my whole school, so it's not like I never saw her).

I then heard her speak once, and spoke to her for a couple of minutes, and an intense attachment was born. I have never spoken to her for more than 20-30 minutes and have spoken to her for more than a minute or so under 5 times.

I am completely and utterly hopelessly in love with her. I can forget about her for a few days or weeks, but she always comes back to my mind. I am so utterly obsessed it's horrible. She doesn't have social media so I can't look at photos or videos of her, I just remember her in my mind, and I don't even speak to any of her friends, so I've had zero contact with her. I still can't get her out of my mind. I've NEVER had this happen so strongly - in previous schools, I have been in love with the same girl for years at a time, but then I forget about them as soon as I leave school and discontinue contact (I have never been in a relationship with a girl I've been attached to like this, and I am far more attached to her than previous girls, including one who I was "in love" with from ages 11-16).

I have no idea how to forget her. I've had a 2 year relationship since then, and still thought of her often. I've had sex with other girls, I've kissed a lot of girls, gone on a lot of dates, but she has never exited my mind. I'm 22 and last saw her when I was 18. I feel like I'll still think about her when I'm 30. I feel like I'll think about her when I'm 60. I might think of her on my deathbed.

I can't stand it. I love her so much and can't forget her. The worst thing is logically I know that I barely know her - I have probably spent less than an hour talking to her in total, ever.

Please can someone help me - I feel like I'm meant to marry her and it tortures me mentally. I can't even imagine kissing her because it makes me so emotional I cry - I have never had that with anyone else.

I urgently need advice on how to get over this please. My life feels like it's missing her, I'd rather have her love me than win the lottery. It's ridiculous.

Thank you in advance for any help you can give me.
