Heya
Do you think u'll be able to stay safe tonite? If not, maybe you should ring your local crisis team and discuss it with them?
But for the time being, maybe you can do something you enjoy, or previously enjoyed? May it be writing stuff, walking around the block, tv or music
When it comes tomorrow, i'll suggest u to visit your local GP and see what the docs say. It might lead to a referral to an Psychiatrist for an assessment and yeah, start treatment to hopefully make u feel better.
Hope that helps a tad...PM me if need any assistance..
Take care there 2nite
