Having a good heart-to-heart with your close friends helps put what they're going through into perspective and helps to clear up what's going on in your life as well.
You never know if that one friend you always go to, to talk about things might be going though their own things aswell.
Make some time to talk to your friends and check up on them! But over the phone or a voice/video chat please
Being open with your friends makes you become closer i've found!
