<human>: Can you provide a brief overview of the text?

I am 21 yo and have never been in a relationship,not even a short-term one.Everytime i meet someone new that i like ,it never works for some reason.I have tried many things like approaching classmates,meeting people through friends,online dating.Nothing worked for me.Even the guys who showed some interest at first,they soon left.Some of them without a warning!
  

 I am not a very attractive and im trying to come in terms with it.I used to think that when it comes to dating looks are not that important.I have reached a different conclusion from my experience!I think most guys don't see me in a romantic way because of my looks.If i were attractive i would much more luck when it comes to dating.
   
But i'm not planning on dying alone!I'm determined to found someone for me because i believe there is someone for everyone,even for the not so attractive people.After the last guy i dated left me i got so depressed.I got obssesed with him,trying to convince him to stay in my life,acting like a crazy person.I  never thought i could act like that,i never thought i could get so desperate and vulnerable.I think i hit my bottom,but i will not allow myself to be depressed anymore.

I want to move on and leave this part of me behind.I don't want to be that girl ever again.I will try to recollect my confidence,go out there and find someone.I want to be strong and prepared for as many rejections as it takes to meet him.

At this point i need motivation and most importantly advice.I was thinking of trying online dating(have tried before but was too afraid to fully expose myself.I was usually hiding behind random pics and when guys saw my real pics they clearly didn't like me).I think it's an easy way to meet people,and eventhough it didnt work for me in the past,i have a good feeling now!

So,basically this post is not my attempt to ask sth,except of advice.I just wanted to share my experience with people and maybe find someone who has been in similar situations.
<bot>: I have been single my whole life,any attempts i have made to change that have failed so far but i want to leave it all behind and make a new start.Motivation and advice always welcome!
