hello and welcome to ehealth!
well the relationship thing you mention is normal. if you really like and have feelings for someone you cant just let them go. it takes time and all people move on at differnt rates
happiness is something YOU have to obtain for yourself
its not something that is just thrown your way
life has a funny way of saying "i told ya so"
so the bad things in your life that may be happening now are SURELY happpening for a reason..and months,years down the road youll look back and say "whoa! thats why that happened!" because your life will eventually fit together like pieces to a puzzle
dont try and kill yourself
whats that going to solve? you said you regret attemting it befoe right? how did it feel when you were in the hospital knowing that you could die any moment?
didnt that scare you?
live your life no matter how hard it gets no matter what happens. take the bad and good things and turn them into something wonderful
one day youll look back on it and realize you are meant to be here and that things play out for a reason
if you need anything
im ALWAYS here
