Would like to talk to someone.. I feel so alone :(

These past few weeks have been horrible and I find myself getting upset at random times for no reason :( I do have terrible thoughts sometimes but have never acted upon them.. Writing this in tears :( just looking for some advice :(

Edit: Spoke to my parents and told them a lot of my thoughts and feelings but couldn't bring myself to tell them the heavy stuff.. We are going to book me in with a doctor in the morning to hopefully get some kind of help!
