Edit 1: I have received a lot of great answers. I am not accepting any answer because I think there might be in future that some user want to contribute any new answer, as in my opinion some users might find the answers useful to them to keep their head high in time of despair. Thank you very much to all!
I am a person living in a 3rd world country who has done a master's in mathematics and is preparing for grad school in math. Unfortunately, I fell into depression due to horrible harassment by 2 professors against which no action could be taken due to nepotism and corruption in my country, family issues and had to take a break. I don't get much support from my parents or friends as research in mathematics doesn't yield much money and there are a lot of other high paying jobs. I don't care much about their opinions. I live in a very very capitalistic country and people here respect only money. I like to study mathematics as I am very much interested in it. I am taking therapy and medications. I have realized that I need some motivating instances to help keep me going and so that I can motivate myself when I am low due to my depression.
It is my humble request to you to suggest books, websites, and/or blogs of real life instances of mathematicians overcoming challenges and hardships in life, both mathematical and non-mathematical.
I have been reading Men of Mathematics by E.T. Bell but it is mostly about mathematicians of older centuries, not the 20th and 21st centuries, although it's still very good read.
