Stop selling yourself for nothing!  
You are the one to put a price, a standard for everyone to respect. if you don’t respect yourself, no one else will. Choose your friends and people carefully;  think which are the ones worth investing in. Don’t waste yourself on anyone. I know you say you have to love everyone, and that is true, but loving someone and investing with love in someone are a bit different.
Think about it – they need it –  They deserve it, e
ncourage all the time!  Humanity needs more of that! You know how much you miss it, then?! Do it!
