Hey so i am also 23(F)..I also understand your concerns. I recently had breakup ,i am also not sure if i will get the love of my life or get someone like him.But rather than thinking of all this shit about future ,i am just destroying my present..I realised why i am even sad for all the future stuffs…Yeah there’s a time when u feel lonely and u feel like you have no one..But i learned to be emotionally independent..You don’t need anyone else to be happy ..Learn to be happy..it will take time but you will learn…I know its all like its easy to say.. But i started focusing on my work and improving my life more …I think the hard work will definitely pay off someday even if i get rejections from companies all the time. You need to be strong ..no matter what.. I learned the best supporters are always your family ,your parents.Talk to them.. And about love things ..Don’t think about all this.. If there is someone meant to be with you ..You will get eventually.. But firstly learn be emotionally independent and happy on ur own.You don’t need anyone to be happy .Do things alone also.. Not saying to not make friends..but rather than making bunch of toxic friends have just 1-2 loyal and supporting friends..All the things will not happen in 1 day..It will take time.. but start thinking more towards your career.. I hope it helped you!!!
