My girlfriend of a year and half has broken up with me . We’re only 18 and we’re each-overs first relationship/sexual partners.She broke up with me because she was no longer romantically interested in me as she never wanted to have sex , never flirted with me , she didn’t feel a spark, she didn’t feel exited during the relationship when we saw each over .But I was the complete opposite I always got exited to see her and always wanted to see her as much as possible, always wanted to have sex and I still felt a spark . She changed my whole lifestyle as before I didn’t go out with friends that much but she pushed me to do so many things and now I do go out more . i love her to bits and without her I feel as though i just don’t want to live any longer.
For a long time I’ve felt really low because Im really insecure.There has been occasions where I’ve found myself attractive but I just wish I was taller and built bigger and I just generally don’t like who I am as a person. She tried to help me with this a lot but she isn’t the most emotional or supportive person so sometimes the advice she gave wouldn’t help but she did encourage me to go to the gym etc which made me more confident for a short while when we on holiday.
I feel lost because I don’t see a future as the person who I want to have a future and thought I would marry and grow old with can’t be with me.I feel worthless as though I’m not good enough for anyone because the person I love doesn’t want to/can’t be with me so what’s the point in me even being around. I just know I’m never ever going to be happy again and even if I do get over the breakup I can never see myself being as happy as I was with my ex.I constantly feel exhausted and tired of trying to live.I feel as though there’s no point in me trying with anything in my life at all as before it was all for her so that she could be proud of me , everything I tried for was all for her as she motivated me a lot so I’ve just got no passion do to well at sixth form , get along with my family , go to work , get out of bed without her .I feel regretful and annoyed at myself because I could have done something to stop her feeling like this but I just didn’t notice but she says it’s nothing to do with me and it’s just her feelings towards me have changed.
I just really love her and can never see myself getting over this so I just don’t want to be here any longer. Please give me any advice on how I can improve how I feel because I’m at rock bottom.
