Depression/anxiety?

I'm generally a happy person. I am very independent.. I've been told that I'm an empath.. it's the energy of others that is overwhelming. I have social anxiety. Rarely but occasionally something small will spark suicidal thoughts. I like to think that I'd never act on them. But it's just where my mind goes.. am I bipolar.. depressed.. is it just anxiety or an over reaction.. sometimes I think that it's an over reaction but idk how to breathe. Like how do I cope in these situation without attracting attentions... like how do I pull myself away from the cloud of thought.
