It sounds like you're doing all the right things and have your support network in place. I didnt mean to brush past how you feel right now. I know those feelings and my experience was I just had to endure it. I agree with the others that you're not being too sensitive. You're as sensitive as you are and theres good reason for that and sensitivity is one of the things I never could change. I dont think I want to change how sensitive I am, just learn to manage it better so I dont get drowned by all the things there are to be sensitive about.

It takes time but you can learn how to work with your sensitivity in a way that makes you feel like your sensitivity has a valuable purpose and by channeling it in a healthy way you can work on bettering the situations that make you feel awful. For example, you may be sensitive to child abuse because you experienced that or have empathy for a friend who experienced it. You can use your sensitivity to fight abuse against children and in that way you accept your sensitivity but also make positive use of it.

First things first. First become strong in yourself, then work outwards. I acknowledge that you feel awful right now and I hope you can work through it in a way that is peaceful towards yourself and also provides a benefit to your future and community. Sensitive people have great value in life but I know it can really hurt too.
