My heart goes out to you. I can't imagine your pain, not only for having experienced abuse but also to have people trivialized or maybe not even believe you could be hurt by it, particularly when it's by people you bravely reach out to for emotional support like the listeners here. Every human has a mind, emotions, and a body with which to be hurt deeply. It should be considered seriously, no matter what your sex or gender. Your abuse was real, the pain still hurts, and you deserve to be heard properly.
I'm sorry this happened to you. It isn't right. It isn't fair. I have found most listeners I get connected with don't even follow the basic guidelines of the listener's training, having done the listener training myself. If there's one thing I would encourage you to do, it's to find a respectful therapist in your community or online who knows men can be hurt, traumatized, and abused just as women can. Seek out therapy groups for abused men or in general. See if there's a mental health organization in your area and connect with them to see what resources are available to you. Search for open-source therapy groups online. Look up mental health organizations and hotlines that apply to your situation and make full use of them. Learn coping skills via the self-help section, under the Path drop down. Join the Trauma sub-community, if that makes sense to you. Don't allow all your care and coping to be limited to 7cups listeners, for whom finding a good listener for any issue seems to be a low probability. Your mental health is too important to leave up to just a gamble.
Keep trying and please don't give up on yourself. You're a worthwhile human being. I believe in you. You can overcome the pain you've had to endure.
