Recently i've had a new feeling i've never experienced before. many times because of immediate feelings being so bad.

However...now it's not so much the "right now." I don't have any immediate plans, . But, I do feel like I don't want to live anymore long term...if that makes sense? I've found myself wandering off during the day wondering how much longer before it's time to throw in the towel,

I don't understand it. I've been overwhelmed before but this seems more like an overall end. I really have a lot I want to experience still. I'm still continuing on with life, but I don't feel like I will make it . I just got back from Mexico. Who can sit on a beach in Cabo during spring break and want to die?

Any idea what this change in thinking is, or advice? I'm worried, but like I said I don't feel like I want to go out and do something stupid.
