It does this all the time. My depression comes and goes whenever it pleases. And i don't know why. I can be totally fine one minute, and the next I will be completely depressed. I don't know what triggers it, or how this even happens. I've been really stressed lately. My dad is leaving us because my mom cheated on him. And my mom is acting like a teenager. She doesn't acknowledge that I have a problem, because her mom was in a mental health hospital, she says it's too much to deal with. And I get it, but that doesn't mean that depression just goes away. Just because she ignores it doesn't mean it's happening. Everybody in my house has started drinking again. Even my older brother who is usually my person to talk to. But he's been different lately, and I just can't. I'm on summer break and usually just talk to my school counselor during the school year since she is the one I went to about my suicidal thoughts over a year ago. But I can't control it. Is it normal for this to happen? For depression, and suicidal thoughts to come and stay for a month or so, and then just leave for a couple weeks? It's stressing me out and I can't handle it at all.
