I am depressed and lonely... far away from my family and friends..?

Ive been away for awhile ... I live in korea right now... ive been depressed and lonely for a while now and only getting worse... Now i meet alot of people and hang with a few people all the time which i love to do... but i still am depressed... I go out and meet a girl ...get their number... we hang out... and we have fun...but many times we never really see eachother again... i dont know why... i also think im insecure... if i call a girl and she does answer or respond... part of me thinks that shes avoiding me... Like last week i hung out with this very cute asian girl... and we did a few things... its like i like them already... i might just be really infatuated which is probably the case but also i havent had a girl friend in over a year and ive been gettin really lonely lately and i get more depressed when i see these creepo guys with girls...and here i am ...alone... ughhh i dont know... im too scared to kill myself so thats out of the question but damn this sucks
