Excuse the ranting, but Everything. Sucks. Right. Now.
I've just realised that you can't depend on anyone to help you feel better, try as they might. It's limited what others can do. Meet for a coffee? A meal? Hang out with you for the afternoon? Chat with you online?
But at the end of the day, no one can really be there for you 24/7. Everyone has their lives to lead- birthday parties to attend, dates to go on, dinners to cook, chores/work to finish, other friends to hang out with who aren't miserable company.
It's impossible to expect anyone to think about you constantly, to worry and fuss over you all day long. (Yes, even mothers are human too.) And it makes you think, what's the point anyway?
Ultimately, you have no choice but to rely on yourself to hold it all together and not rip apart at the seams. You are the one who has to take care of yourself, and sometimes it's hard to find the motivation to do even the simplest tasks like making sure you eat or sleep.
It's not easy. And it sucks.
