Depression Treatment Care

I’m ALWAYS fatigued, yet have so much energy until I crash cuz I’m so tired.
I am moderately paranoid.
I have constant shortness of breath, sort of like asthma, but I’ve tried inhalers but they don’t work.
I talk very fast.
I’m scittish.
Have bounds of happiness, then sadness for no reason.
Can anyone tell me what’s wrong? I hate this. I’ve had it for a long time, now it feels worse, and I have no appetite either.
