Remedy for negative thoughts

Q: I am suffering with terrible negative thoughts - all my life I have struggled with learning and understanding and I’m not good at anything. I have only realized how stupid I am now. I am a mother of 3 kids but now, because of my negative thoughts, I have been put on medication which is not helping. Everything I am saying is true because I am absolutely useless. I don’t see the point of living. I am clueless and so are my kids. I feel so so low. Please advise.

Woman using a tampon to prevent discharge

Q: I suffer with a lot of vaginal discharge for which I may be a mazoor in some months. I am going to check if I am mazoor or not. Now, it may be possible that if I use any kind of tampon or tissue, I may be able to prevent the discharge from coming out. But I do not want to insert anything inside as I am afraid that it may cause infection or cause damage to my hymen.

My question is, is it necessary for me to use tissue etc. to prevent my discharge? Because if I use it I will not be mazoor and without using it, I may be a mazoor.

Inheritance from a property on rent

Q: We were three brothers and two sisters (all married). Our elder brother lives abroad. While 2 brothers and 2 sisters live in Karachi. We have one double story house in inheritance from our father in which myself and my younger brother lived till 2015. When I got company accommodation then we shifted to that house with my younger brother. As mutual understanding, we allowed one sister to live in one portion and another one to get rental income.

Now the issue is that my younger brother passed away recently (30-Jan-21) and he left two boys and one widow behind. His widow is in iddat and has no means of income. So what should be her right and her boys rights regarding their grandfather's house and its rental income.

Please advise in the light of Islamic law of inheritance.
