Feeling Burned Out From Meeting Everyone's Expectations I Think

Me and my surroundings-tehm and their expectations.
Me and my limitations.
We all go through this, you know? Like, it happens almost every day. There are so many situations where we have to find balance between what others expect frmo us and our own limits. It's like a game of how far we can stretch ourselves without breaking. Sometimes we win, sometimes we lose-it's just part of life.

But it gets really tough when everyone arouund you is constantly expecting things from you. If you don't meet their expectations, they label you as selfish or non-adjusting or whatever. They keep pushing and pressuring you to understand them and adjust to their needs while ignoring what you've been through. It's even harder if you're alone without a family support system.

I feel like I'm reaching my limit. If I push myself any further, I might have a nervous breakdown-I mean, I'm not afraid of dying, but the back-and-forth between life and death is too much for me to handle. Why can't others see how thir constant demands are hurting me? Is it so hard for them to show some empathy or sympathy?

Isn't it wrong to take my emotional nature as a weakness?
I know I need to set boundaries, but I don't know where to start. What if pushing back means losing people? Liek, what if I lose my parent who also expects too much from me? How do you create boundaries with someone so colse? Why do I feel like I constantly have to prove myself to others?

I'm just really tired of all this drama and feeling bad about myself because of it. It feels like everyone is sucking the life out of me, and even when there's no more left, they'll still try. I hate myself a little for not being able to handle this better. What a shame!
