I'm going to make excuses to my friend
What is your reason for wanting to make excuses to your friend?
I don't want him to think I'm too sensitive or that I'm crying about the things that are bothering me
If they are your friend then you should be more honest with your feelings. They might be willing to talk to you and resolve any issues going on. Being open with your friends can be really freeing.
Nah I'm going to make excuses and lie about it. I don't want to be honest with anyone.
The issue will never be fixed if you are not willing to talk about it. While it may be difficult to be open about your emotions, just know that it is worth it in the end.
