I thank you for your kind consideration,Am 22 , and i was looking for a job before 4 months, i was about 90 kgs before 5 months. i left my home before 4 months since i need to change my location to search for a job.then i did a course and got a good job in a good company with a good package before 2 weeks. now am 82 kgs, Actually i didn't diet or exercise.but my weight reduced randomly but i know i need to work for reducing my weight.I know a guy who is really really good at heart and he is so sweet.we became friends online. i knew him since 1 and half years.I realized that am in love with him. But i haven't shared my picture, but he use to ask my picture often.And i'l postponed it by telling reasons.He is coming to meet me after 50 days.( sharp 50 days). i need to talk to him and i want him to fall in love .But i can't exercise since its my training period i need to work hard. i'l leave my hostel by 8 a.m and i'l come back by 7 : 30, I'l be so tired. i wont be able to even move, in addition each and everyday i have essment , so i have to study for it.i use to sleep by 9 p.m and i'l get up by 5 a.m to study till 7 a.m , so am getting 8 hrs sleep . i can walk or exercise if i get up by 4 a.m . but i already have dark circles.still if i do that am scared it may become even more worse.He is so good and the only thing is he don't like fat girls.Being a guy he too look for little external beauty in addition he look at heart too. but he is concerned about both the aspects.I'l look good, my friends use to give complements often,Am so worried about my appearance, please tell me some remedy. he likes me a lot.he always cares on me.i don't want him to compromise, i'l do anything for him,to starve or walk whatever it might be.even i'l sacrifice my sleep.i'l make it 6 hrs too. if i don't get dark circles.i want to become thin . atleast i need to lose 20kgs in 2 months. i have lot of confusions.even if i lose 20 or 30 kgs in 3 months will i get love handles etc, wil i get a proper structure, what i need to do to get that. how to get rid of loose skin. i have 1000 questions,i dont know what will give me the best results (tell me whether losing 30 kgs in 3 months is possible)please don't make fun.try to fix my issue.
