U be alrite once you get rid of that " jay shambhoo" thing, bud. Shivaratri ko dinn ma matrai shiva ji ko pooja garne gara, sadhai pooja garne gareko chau ki jasto lagyo :p

sounds like you have gpa problem. if academic is not your cup of tea, go to cheap 4 yr college and get an IT degree. join consultancies asap after graduation. you will be fine.

Same problem everywhere bro. F1 is not student visa; its F**king visa.
You are not one like that . I have seen several person with similar mental condition. Just stay calm and dont take any steps in hurry.
Life is another name of tension. It comes and goes.

 i don't know where u are now but schools in the state of minnesota charge instate tuition to international students also.

 Three major takeaways bro to survive here in the US (My experience). I am still in same condition as you are in and it's been almost ten years. Don't have loser mentality. Everything will be okay. 

Stay focused
Be good on managing time
Self decision

on a side note: ali ali tigdum laauna jaannu parchha. Padhera maatra kehi hudaina yo deshma. Doing right thing at right time. Do cost and benefit analysis on what you do and be proactive. Be outgoing; be a part of career days on campus and try to broaden your network. Just my 2 cents. Thanks.
