It's Not Worth It

My dad and mom came over last few days and visit me. My dad is a very quiet man. He doesn't say a thing, Doesn't scolds us but when he put on the serious face and give us a serious talk, we will all surrenders and cry. My mom is totally the opposite. It's like my mom took all of my dads angry genes and plant it in her self. She talks and nags non stop. She can goes on forever. Both of my parents loves me and my sister unconditionally.
Example. I always make sure i lock my room door when ever i go to work when they are here. I know my mom has this habit to clean. So i actually forget to lock my door this time and thats what exactly happens. She cleans. She hand wash all my clothes. She clears my cupboard. Thats where i keep my porns and dark secrets. That's why i hate it when she does what she does. I'm furious that they do. I got really angry and actually throwing tantrums at them. They too already expected that.  Actually i'm not all the heartless. I'm really touched. I came back and there is a super clean room. Dinner ready and whats worst she has back pain.
But what she does is not worth it. I am grateful but i don't deserve it. I'm not successful. I am not financially secured. I can't give her money. Imagine having a son that is near 30 and still needs her to do all that?? I'm suppose to be able to hire a maid to help her out instead. Or give her money to go around the world. My parents has been living a hard life all along. What i thought i could give , i couldn't and what's worst i have this eye thingy and making me have difficulties at work and actually jeopardizing it as well.
I am just what i am. Having a mid- life crisis at this time really kills me emotionally and i already know i have to climb up. Grab this opportunity and kill the bad luck. What my parents does has touched me deeply, but i really think they shouldn't because it's not worth it. Really not worth it.. I hurt them enough and don't deserve it.
