Idk why but im so scared of becoming depressed and rn idk why i feel a little down, im so scared im gonna have depression

I'm really afraid to say that and the reason might be because of how depression is described to us. And at this point I dont know what is depression. I don't think feeling down is depression. Or sometimes feeling like things doesnt go as you want and you dont know what to do. Maybe it is, I can't tell it cause if i say im depressed in these situations it makes the situation worse, I feel like I put more weight on me. I know its common for depressed people to be ashamed that they are depressed and that might be my case too but as I said, many times I feel like I shouldnt call it depression, just feeling low or things has been stressful and it made me mentaly tired. I imagine depression as a different thing, i believe i was depressed before,because of ocd and i wasnt able to deal with my emotions, and sometimes I spin about that too cause again depression is presented differently in social media and by therapists too. So everytime i feel down i spin about if im depressed, afraid of depression cause I see it as a really bad thing.

I usually would say I’ve never been depressed , but recently in my life since my anxiety/ocd has been so bad and having relationship problems I’m feeling kinda sad / stressed. I keep getting scared of being depressed I keep having intrusive thoughts of “ you’d would be better off if you weren’t living” “ I don’t wanna live if it’s like this” and it’s just scaring me 😞

idk why this is such a recurrent thing for me , I get so scared through the day when I’m not distracted when I think about psychosis. or being put in a mental hospital that it gives me bad anxiety, one time I had a panic attack at the thought of having it 💔 I can’t pin point if it’s intrusive thoughts because it’s a fear of mine .. or not. I think this is the worst thought / fear I have
