1.if trusting ppl alot is ur problem y don't u start trusting urself n work on urself n deal how to b happy within ur company 2)when u believe ppl shldnt have resentment towards each other it's ur opinion n thz gud but not everyone thinks in such way n behave in such so, it's better not to expect ppl wld behave gud smtimes they tend to hurt by any means but try not to get effected or try not to care things which brings u emotionally down. 3)when u can do things for ur loved ones n end up being unappreciated then u shld rather regard it's in vain, when u r dng things even thou u r not convinent then u shld try talking abt ur inconvenience to them, the way they respond to ur inconvenience tells alot wheather is it worth dng for them 4)everyone has their own past flashbacks but it's within u to decide to dwell inthose or rather move out n look forward wts gud. if u study persistently with a time schedule daily n reduce ur over thinking by indulging into work everything changes when u look out for better of u. 5)as u said u r cheerful n interactive u can make new fnds if u don't find the one u trust u can find one !!over by time n it hppns in flow when u meet new ppl until then work on ur academics 6)everyone around barely knows wt exactly r they dng n don't even know the purpose but all it matters at the end of the day is indulge into things u love n try to focus on ur development. thou we r worth enough smtimes we don't get ppl who really appreciate our worth so it's better to find ur own peace acknowledging who u r n wt u want n Wt u can succeed. juz move on with urself, the ppl who r really worth wld come to u

I think you should focus on yourself, set priorities and boundaries. Things will be easier for you then.
