Wishing to die due to not getting proposed

Q: I'm 25 years old living with my parents. After completing my studies I got a rishta from Canada. I talked to that guy for 8 months but it was merely a simple "get to know" talk. They visited us and everything went great. Later, his dad asked for my rishta officially and the wedding date was set. After two months we had to call it off because according to the guy, he was forced into it. I had to bear the consequences.

After a year, another rishta came from a guy in South africa. We connected immediately, he came and we got engaged. He went back and after two months we got to know his PR expired and to extend it, he did a paper marriage.

Also, according to the new rules I wont be able to go there or work. Once again we had to call it off. This time I cant take this burden, I want to die - I hate my life soo much. I dont have any strength in me. Please help.

Irregular bleeding

Q: I am now 41 years old and for the pass 3 or 4 years I have been getting haidh for more than 10days. It first starts off with a brown discharge and after a a day or two I start to bleed for 7 days and thereafter I have the brown discharge again for the next few days. This whole discharge and bleeding goes on for more than 10 to 12 days. Do I start counting my days from the day of discharge or the day I start bleeding and must I go back to following what my past habit was 7 to 8 days a few years ago or do I have a ghusul after 10 days?

Rubbing impurity on the ground

Q: I ride scooters and bikes to school. I rolled over non-halal foods/sandwich packages with leftover foods several times when riding on the streets. I live in the U.S. and the sandwiches are subway wraps with wet food oil and sauce and certainly not halal. Hence, the bike tire becomes impure. When I ride it in rainy days, the water splashes from the tire onto my shoes and pants. Since the bike tire is impure the water splash is impure. I have to go back home and wash them every time I pray and it severely impacts my life. However, I heard that walking or rubbing impurity against the ground makes the impure shoe pure. Does this ruling apply to a bike/scooter tires? If so then the bike tire can be regarded as pure as it rubs against the ground so many times?
