How can I make my family understand that I'm not seeking attention and just trying to get the help I need?

you can try to explain to them and open up , do not be afraid to tell them how you actually feel about everything

There is a difference between "attention seeking" and "care seeking".Unfortunately, when we are looking for help or care around us, this can often be seen as seeking attention, even though it's not and we know that.You could sit down with your family or write them a letter to help you explain how you feel about it and what you need from them.

Try to define as clearly as you can what issues you are trying to get help with and emphasise that any help and support they can offer will always be appreciated. People thinking you are seeking attention often stems from a feeling that they will be imposed on. By reassuring that support is appreciated but optional you allow them to make the choice to support you in whatever capacity they feel able to and this in turn often leads to more support than would have originally been offered.

Open communication with others is one of the most beneficial tools I've used to tackle difficult conversations in all areas of life. Ask family members if they are willing to support you and let them know how they can be there for you to create the opportunity for dialogue.

Assuming you have already tried to communicate effectively, a more enforcing way would be to engage a third party, likely a family counselor.

Explain to them that you would never fake something like this and genuinely need their help right now.

People get busy sometimes and are often times on autopilot, perhaps you could sit them down and explain to them that you need their help?

In my experience, you have to explain your emotions and troubles out loud, or in a letter, showing and listing symptoms, technical terms, and generally trying to be professional about it. Tell them you are not seeking attention, you really need help, and that it's generally going to help you succeed in life to get this help.

Talk with them and explain how you feel, say exactly what you said here and i'm sure they'll know you aren't seeking attention

Try talking them through what you're thinking and feeling. Sometimes when we act certain ways the people close to us won't necessarily understand why we're doing so, so sometimes they can end up with the wrong end of the stick and think it's something other than what it is. I would encourage you to speak to them and try to set the record straight. That way they may also be able to help you get the help you need
