Strive to be a better friend so you attract more loyal friends. Look at the healthy friendships you have mutually enjoyed and learn from those. Learn to be a better you by not allowing yourself to get caught up in drama at work or at home. Let go of unhealthy relationships. Do not get caught up in a toxic circle of doing negative things because others do them. You will not find friends that are trustworthy if they cannot trust you. When you say you’ll do something, do it. If you make plans with others, follow through with them. Doing small deeds can go a long way to helping you build trustworthiness. The only thing you have absolute control over is you. You get to decide how you react to certain people and who gets space in your life. You do not have to remain friends or even friendly with someone just because you were friends since you were kids or you happen to work in the same office.  If you find work friends are harder to trust because of competition at work, make clear boundaries about not bringing work home. You do not have to be friends or social with co-workers if it is only leading to problems at work. The same goes for friendships you make in other settings. Are these people positive influences? Are they using you? Look at the types of friends you have and the kind of friendship obstacles you encounter. Maybe it’s a good idea to reevaluate all your friendships to see if you are making smart, healthy choices in your relationships. This includes hiding things about yourself or family just to keep certain friends. You may find friends act differently in certain contexts and that you cannot always depend on certain friends to be consistent. If you lose a friendship because you need to focus on family, then it wasn't a healthy relationship to begin with. This also includes ignoring the actions of a friend in the name of friendship. You have the right to stand up for your beliefs. In addition, you should not be pressured to look the other way if a friend does something you feel is wrong or violates the law.
