I Have Cared Too Much About People Who Didnt Care For Me

it's best to not direct your time and efforts/attentions toward such types.. eh?

You can turn this around. its never selfish to start doing you a bit more and others a bit less, until you really and truly know that they appreciate you. That takes time. A long time. But it's worth it!

Sorry that you are feeling like this, who is doing this to you?

Do you want to use my phone charger

Same here and those people are not worth my time
