I dont know what to do

My mom just had a talk with me, she also has depression and some other stuff. But she was talking to me about how she is seeing sighs of mental health problem in me. She gave me till she came back to the store to tell her sometinhg whether i think/want help from a facility, i want to fix it myself, or i am willing to talk to her. I have tried to work on myself, but it only helps for a day or two. And how can i talk to my mom directly if she is part of the problem? She tries to understand what im going through, but she is just really overprotective and judgemental. She asked me whats wrong and i didnt even have the courage to speak up. My mind was telling me what to say, but my mouth just said "im tired". She said it seems like there is a disconnect between me and my family. I know that and try to fix it but it just seems like fixing it is so much harder than letting it be. I know when she comes home i wont say anything besides want help from outside, but i know shes going to question me. She does that all the time. She questions everything i tell her and i usually just sit there and listen. I dont know what to do.
