We all get there, honey. Just try to take a step back, gain perspective, and remember the important shit in life. Your health, first and foremost. Have you ever held the hand of somebody you loved as they worked their way through stage 4 cancer? I know that is dark, but every time I start to think my life is getting hard, and unbearable, I remember those moments, having to see my somebody I loved so fucking much fall apart in front of me and not be able to do a damn thing about it.
Love – relationships – jobs – money – all that shit pales in comparison to not being able to watch your kids grow up, or see somebody recognize that they are not going to be able to.
What you are going through might be hard. But it can always be so much worse. You have air in your lungs. My guess is the people you love do too.
Count your blessings. There will come a day when you look back and wish you had the problems you have right now.
