Hi Nicky,
I too was diagnosed at the age of 15 and I know what its like to have Psoriasis at that age but as for meeting a partner dont worry cos when you meet the right person they wont care if you have P or two heads they will love you for who you are, this site is full of P sufferers and most of us have partners and families , what has your GP prescribed ? and remember if it gets too bad you should ask your GP to refer you to your local dermotologist
