I am sorry that you are feeling so depressed and alone.
I hope you know that you aren't alone here and that I care. Others here on RYL care, too.
*hugs*
It sounds like you are dealing with some really intense emotions and I can't image how hard it must be to hold it all together when on top of it you are exhausted. I know when I am so tired of everything, it makes just about every issue seem worse and like I just can't deal with it.
Hopefully you will be able to give yourself some selfcare, maybe some rest, and hang in there. I know this isn't going to fix your problems or take it all away, but when you are rested you might feel just a little more control. And sometimes a little control can make all the difference in what you can handle.
Please share more about what you are going through if you want or think it will help you. Post it and get it all out, or private message someone, me if you'd like. You can send me an email if I am not logged on here. I check my mail at least a few times a day.
Please be safe and know someone does care. I hope that helps you to feel less alone.
