Tired

I’m just so so tired of trying so hard . I am just tired of everything. College , family , friends this would be the part where most people would say they don’t care anymore but I do and I think that’s what’s worse . Is how much I care and I just feel like this sadness inside of me is just ruining my life . But it’s not just that I also feel like I care too much . Like I’m tired of caring more for others than they do for me . Life just really sucks at the minute and I don’t know the cause my sadness and that’s what’s worse how do you find a solution when you don’t know what the problem is . I have some great friends and I know they’d be there for me in an instant but i just feel so bad when all I do is talk to them about how I’m feeling. I hate it so much . I feel like my mood just flips like a clicking a switch and I don’t know how to turn the lights back on. How do I get out of this darkness???
