There's nothing wrong with you needing help to thrive compared to others. You might've heard this before, but everyone has their own needs that need to be met, and there's no shame in that!
Where everyone in my family ever went ot therapy and yet they're managing fine. Its like, despite all the abuse and generational trauma, they manage to thrive without needing the help like I do
I don't wish to assume your family situation, but it could be possible that they simply look fine on the outside yet deal with their own demons on the inside.
Makes me think something is wrong with me for needing this much support
Everyone is different, so everyone has different needs. Usually, those who receive more support become incredibly great individuals. Think of it as if you're a plant, you require more attentiveness and support during your growing process, but you bloom into a unique and gorgeous flower. (My metaphor skills are bad, so please forgive me if this comparison is equally as terrible.)
Although, I understand where you're coming from. While I have not received therapy and am not medicated for any mental illnesses that I might have, I do struggle with depression and issues of self-worth. This is a stark difference from my parents (both of whom lived in difficult situations) who have secured good jobs for themselves and live comfortably as upper middle class individuals despite all the trials and tribulations they've been through. I usually felt ashamed that I needed support (though, in this case, it's material support) in order to get to places where my parents have been without it, but eventually, I realized that everyone needs different things in order to "thrive" in their environment.
Sorry if my whole rant didn't help with anything. I hope that you're able to prosper and find what works for you.
