I was in your position in December last year my ex just dumped me, all my friends were at uni and I found it impossible to move on becuase I had nothing to keep my occupied, i felt like everybody else was moving on with their lives but me. I kept clinging on to stuff i had with him as I was unhappy and alone and when i was with him i wasnt. I was in love with the idea of him not actually him.
Time is the only healer, its so hard but you MUST cut contact, my ex texted me alll this time i was feeling low and i just couldnt get over him at all and hen i found out he had a new girlfriend it killed me. I started working a hell of alot more hours, I began gonig to the gym every night after work, doing aerboics, yoga, sports and met people through that, i made a massive effort to be more outgoing and social i became friends with people at work who were in their mid 20s but started being invited to nights out and the pub and so forth. If your unhappy in your job change it for something more social like a bar/pub job there be so many people your own age and the job will be a good laugh.
The prospect of uni also kept me positive i am going this septmeber and when i felt **** and saw stuff about my ex i thought im going to meet so many new people at ni he will be a distant memory.
I ended up meeting my current boyfriend on one of these nights out and now im friends with his friends and their girlfriends its like i have a whole new life. I was dreading my ex coming home this summer as i knew id have to see him and see him with girls and i was worried i wouud want him back, hes been hoome for ages now and i couldnt care less for the first time since septmeber I can actually say im fully over him
Time is the healer, but surrond yourslef with things such as a new sport, a new job, make new friend, revamp your image and yourself and you will get over him
