Sinking

I just feel like im drowning all the time. No, not drowning, sinking, rather. Silently sinking without a sound, with no one noticing. But then i guess i deserve no one noticing, since im quite possibly one of the worst friends ever to all my friends and im pretty sure my boyfriend is getting kind of sick of me as well. I just feel so depressed all the time, and its not like a really have much of a reason to be feeling like this because like ive never been abused or anything so its so stupid that i feel this way but i just dont know what to do and i have no one to talk to and all ive been thinking about these past few days is whether ending it would be a good option
