Fake friend
We've all come across this type of person, the symptoms are very hard to notice, it only becomes noticeable when they start to lower down their guard. An example could be the supposed friend compliments person A, and as soon as that person leaves they reveal their true feelings of them, there are many examples. Overall the individual doesn't express their true emotions, this type of person is not direct, which are signs that you should consider breaking away from them.
Judgemental
The judgemental friend, who is different than the fake friend. They are honest with their feelings, but someone who constantly critics you, a friend is supposed to support you, and laugh along with the silly moments, not a judge who weighs out all your faults.
Clingy
It's great that you and your friend are close, but there needs to be space. This type of person loses out on allowing their friend space to do other things, or hang out with other people, it's ok if you see them, but not every day- give them space and not try to control who they see, or what they should say. Overall you should question yourself, is this a romantic relationship or friendship? If it's the first, consider speaking to the person, if they don't respect your feelings, time to say goodbye.
To all those who read are reading this, yes there are these types of people who you may or may not have in your life, sometimes it is better to walk away from a person who complicates your life, or even creates a negative atmosphere. It is not being cruel, but simply being mature and realizing you don't need these type of people in your life, simply wishing them well and walking away.
