My head is taking over my life

Im a very shy girl which has always bothered me. I got bullied right through education. I've grown up and I'm now 22 a lot confident than I used to be. I don't have many friends an odd one here and there, no big groups or anything like that. My weeks consist of work (which is my life) I'm a farmer and I picked this job so it comes with consequences but I did pick it, I want to take it over so getting up at half 5 every morning is a must. I get fed up at times just because I'm not like others. They have groups of mates, boyfriends and even kids now. I haven't had any of that and I feel like a loser. My parents have given big hints that I should be looking or have someone they mean well. And I agree I should but I'm so reserved it's un real, it's so hard for me to be out there, I've tried to change so much but I can't this is who I am :( I go to different groups and the gym and put myself out there doing things I'm comfortable doing. But my sister is 18 has no trouble at all and is out every night, I'm in most nights and have no where near as many friends. It gets me down really down. I don't feel normal at all.
