Parents are just taking my savings money

Hi, I am confused, frustrated, angry, so need some advice about the things happening with my parents.Sorry if it's a long post.I was married when I was 19 years old, it was an arrange marriage, where my parents had got me married, sadly, my husband passed away in an accident within a year, and I have a son.Later, I graduated in Computer Science Engineering, finished Master's in USA, got a job.My main aim was I wanted to be independent and wanted to take care of my son.Since the day my husband passed away my in-laws didn't bother about my Education, about me nor my son, but my parents supported me for my education, took care of my son while completed my education.In the meantime, whatever insurance money, fixed deposit that was given to me for my husband's death was taken by my parents, and I didn't bother because they were taking care of me and my son.Later, when I came to USA, I chose an University where I could work as a Teaching Assistant, my course fee was waived off, and I was able to easily manage my living expenses.Later got into a job, and I started taking care of my responsibilities(i.e son's education, other expenses, I can even sending money to my parents expense), along with that I sent them Rs.12,00,000 as a gesture for supporting me.And, parallelly, I was sending money as savings for my son's education to purse his career in Medicine (MBBS), he finished his NEET 2020 exam (it is a entrance exam in India to get into Medicine similar to MCAT in USA), now when I am asking for the money they are not at all responding, this is causing me frustration, anger, this was the money I was saving for his future.Right now, they are constructing a house, which is going to be written on my brother's name, although the plot was bought by my parents, my brother is financially sponsoring for the construction of the house. but I already I was sending the money that they are spending for my son, for their expenses, already gave them huge amount of money, also I didn't ask for the money they had taken which was given to me by the insurance company due to my husband's death, still they are behaving like this.I now have to pay for his college fees, I wasn't expecting anything from them, I wanted to be independent and did my best, still they are doing like this. Every time my mom emotionally blackmails me telling that she made so many sacrifices took care of me and my son, and didn't leave me in my in-laws place, and now that I am earning I am not caring about them.This is reaching the limit, I am getting frustrated.They never thought how I would feel, after going through all this, it takes immense toll on me as well.Now, I screamed at my mom, messaged her for all their wrong doings, and I am not speaking with them any more.There is a limit for everything, why don't parents understand about what their kids are going through, why do they always think about their problems first, and keep on reminding me about the sacrifices made for me, and also discussing about their sacrifices among relatives as well.Not sure if I am a bad daughter, but one thing is that whatever they are doing is not right, just because they took care of me, and my son doesn't mean they have all the rights.Now, I am worried about how I am going to pay college fees. via /r/AsianParentStories https://ift.tt/3758cJI
