I will try to make it short.
1) A lot of things that happens in our life is related to kamma, what you going thought majority of people will go through. Unless you have enough merit to turn your life around (which is something you test through actions)
2) There is no solution to that situation. If you are looking to prosper, you need to possess a set of skills, wisdom, and a strong character/physical appearance/connections to be successful. Each area you lack will work against you in one way or another. Being on top or having an advantage in life brings another set of difficulties, and now you need to manage your position. The best way is the ability to stabilize your life so you can focus on Dhamma, so not going too high and not going too low in terms of income, household, and ability to maintain that.
3) Your personal feelings, stoic stuff etc,. They are all mental fabrications, you see images in your mind related to yourself and the future, and suffer that while in reality it is self-maintained and fabricated delusion. All you need to worry in reality is basic stuff, practice Dhamma, and listen to discourses so you can get rid of that fabrication. In reality, there are only two states: you are either free or in bondage. All the loneliness talk is just hormones and biology pushing you towards action, desires. You are mismanaging your mind, rather than just going back to the basics. Refresh discourses (the one I posted somewhere), re-read stuff, and get your strong base otherwise you will crumble as you actually are crumbling because you’re flying too close to the sun without understanding what it takes.
