(((hugs))) looks are only skin deep, ok some people do judge on looks, but the friendships that last do so because of personality, caring nature, thoughtfullness etc. just remind yourself that looks are the first thing to deteriorate and the easiest to disguise.
your skin and bones are just the structure which keeps all the goodness in side safe. would you choose a mouldy rotten sandwich in a beautiful wicker hamper or a deliciously tasting sandwich in a paper bag? most really good looking people are shallow with little personality and even fewer morals, do you really want to be in that category? I too am definitely no looker, but i am proud of my morals, patience, kindness etc.
everyone has hangups about some part of themselves, they are lying if the say they don't. try writing down all your good qualities and bits you like about yourself, then all the bits you don't like about yourself , you will probably find there is more good than bad (unless you repeat the bad ones in different words which i have been known to do when really in a bad place!)
work on expressing your good qualities and less on worrying about what others think about your bad bits, you will find a few people will begin to recognise and respect you for these. but bear in mind that good friends are one in a million so it may take some time for your paths to cross.
if you can, try asking at a make up counter in a department store for some advice on which products will suit youy best, the assistant will usually be happy to spend time with you or even applying some for you, all the time she will be trying to make you feel good by complimenting you and giving tips on disguising any flaws. When she is fininshed her sales pitch you do not have to buy the products, just make out you are not quite sure and will think about them! this is the start of helping yourself to feel good about you again. positive comments from a total stranger often feel good as you know they are not going to be *****y for the sake of it.
