lonely again

So I really felt like a third wheel tonight. it is hard to be the only one of your friends that doesn't have a boyfriend or girlfriend or husband. so when i got to kroger adam and rach were all over each other and so was jd and cherellie...so i felt so out of place. so i went inside because i felt i was in the way...i normally don't feel like that...but normally they don't hang and kiss like that so i felt like they wanted to be alone...and that kinda hurt...i am lonely but that just isn't something i can fix right now...i am 26 living at home with my parents i broke up with my last boyfriend but still don't feel right... i am not sure why i have not dated..i think i am a little scared that i will end up the same way so i feel like i am saving me and the other party involved a lot of heartache...it is tough to see my brother and his girlfriend hanging all over each other and knowing that he had his heart broke and he just bounced back and got back in another relationship i don't know how he can do it...but he is a guy maybe that is it...i don't know...i feel like i am not complete...i am missing something and i don't know if it is something that someone else has or if it is something my ex has...i know that i broke up with him but i think it hurt me more...he was my first true love and i thought we would be together forever( i am glad i was wrong) but i gave him my heart without a thought and now i regret giving it to anyone...i don't know...i don't like to feel like a third wheel but that is how i felt tonight and so now i feel ugly and lonely...
