I struggle to get along with my parents... may Allah guide us

As-salamu alaykum sisters, There is almost always tension between my parents and me, especially with my mother. I don't know why. I feel like such a difficult daughter. I cry a lot even over small disagreements or inconveniences. When I was away at university, my parents seemed happier and the house was more peaceful. After I graduated and returned home, it feels like I've upset the balance. I'm someone who gets easily triggered by different things - negativity, bright lights, noises, etc. Maybe that's why I'm on edge at home most of the time. I don't understand why I feel so low as soon as I walk in the door. I worry I'm not good for my parents, and at times I feel they aren't good for me either. I love them so much and alhamdulillah they try their best; I can never repay them. I fear I'll never be an easy, untroubled daughter. Since puberty I've been a crybaby and struggled with depression (undiagnosed for a long time, later confirmed). My mother dislikes when I say many things are because of my depression; she says I'm labeling myself. My mind never stops - always defensive, always on alert against itself and the outside world. Sometimes I say I want to die, then I cry for saying it. I imagine living like this, fighting many battles and waiting for death: trying my best in deen while dealing with depression until the end. I wonder whether marriage might fill the emptiness, then I worry I would ruin someone else's life with my struggles. I don't have answers, sisters. I don't even know if anyone will read or reply. My life seems to be drifting and I feel lost. May Allah grant us ease, strengthen our iman, heal our hearts, and help our families. Ameen.
