What should I do about my brother's constant mental abuse?

First off Kudos to you for trying to hang in there. I would have left WEEKS AGO. Now that I have stated that it seems to me you should just one day when he is gone just pack up and leave. You have a job and support yourself along with his bum self. I mean my little brothers and I are by ourselves and they BOTH have jobs mind you they are 10 and 14. I mean sure the 10 year old doesn’t make much he just mows lawns and trims hedges and what not but he still helps with bills when we sit down and do them. Maybe if you left he would see that you’re NOT always going to be there for him when he needs you if he continues to treat you like this. I feel his confidence is driven by how scared he is which explains why he is somewhat controlling too. Mentally you are in a VERY UNHEALTHY living situation and I would advice you to LIVE ASAP. I mean even if you talk to the land lord I am sure he could even help you out in getting your own apartment. Anyways if you ever need anything I am only a message away. :-) Good Luck! <3

Congratulations on your recent weight loss Cintia! {:^D Keeping up your healthier habits during this stressful time is a sign of real strength and maturity.

I think your plan to contact your mom is a fine idea for you to pursue. But it’s not the only one. As Stasha and Kal said, you could look for a place of your own. If you think it would be hard for you to do that independently, you could look for someone to share a place with. Or you might be able to take over your current apartment from your brother. If the lease will be up in May or June, maybe you could hang in there until then, and renew it in your own name. Otherwise, maybe you could find a temporary place (month-to-month rental, or a friend to stay with), and let your brother lose the apartment because he can’t pay rent; then go get it back. For any of these options (except living with your mom), it would be good to speak with your landlord first, as Stasha suggested.

Meanwhile, as long as you are living there with your brother, it is very important that you stand up to him and assert yourself - non-aggressively, of course. You do not have to do what he tells you. You can tell him he has no right to speak disrespectfully to you. You don’t need to get into an argument with him about it, or to reply to his arguments or insults. Just state clearly what you want him to know, and then let him rant as much as he wants about it. When he is done, firmly restate the same clear message for him. It’s best if you have a backup plan in mind when you do this, but you can still do it even without that.

If he does any violence against you, or against the apartment - or if he threatens violence in a way that puts you in fear for your safety - call the police immediately. If you can’t call them safely in his presence, leave and go to them. Family loyalty does not extend to accepting physical or emotional abuse. Letting him believe he can abuse you (or anyone) with impunity is a way of abandoning him to whatever inner demons plague him. Only by standing up for yourself can you do him the favor of motivating him to seek the help he needs.

Thank you guys for answering my question it means a lot to me, I will take your advices!
