how do I get over the feeling that my friends will turn against me/leave me?

I think it is wonderful that you love your friends, but you shouldn't feel like your struggling to hold on to them. True friends will be cemented to you. Be yourself. Don't feel like you have to try so hard. If you lose them by just being yourself they weren't your friends to begin with. Or you might just be psyching yourself out. Just be the best friend you can be. Also, make sure you are getting out there and making new friends constantly. It's a good idea to surround yourself with a bunch of friends that way no matter what you will never be lonely.

Getting over feeling that your friends will turn against you is serious one. It starts with you loving yourself. And in the process of loving yourself let the same love spread to your friends. Also, there is a need for trust. When a level of trust has been built with your friends, the feelings of them turning against you won't be so real to you anymore. Third, be open minded with your friends. Doing this will enable them to tell you their minds and what they feel about and you will know the possibility of them turning against you. Conclusively, don't forget that it's a feeling. Your steps and actions will determine either the feeling will become a reality. Therefore, act right!

Learn to be secure in who you are and what you have to offer as a person/friend. Understand that you deserve healthy relationships and friendships. Seek out individuals who are trustworthy and have good moral conduct. Friendships are bonds that take time to develop. Once that bond is strong, your anxiety about friends turning against you will be reduced. You will also better understand that when/if someone chooses to leave for whatever reasons that they have, sometimes it is for the better. Some people are only with us for a season. Others are with us for a lifetime. Finding out who is who sometimes is the challenge.
