I am sorry that you're going through this. I'm not an expert, but I think that if you're having such thoughts, then yes, they are in the realm of "suicidal thoughts". I'm not trying to scare you. Suicidal thoughts don't always come in the form of "I want to kill myself". I don't agree with whomever told you that this is "normal" because if these were "normal" thoughts then the act of suicide would be ok....see where I'm going with this?
I have had those thoughts where I wanted to hurt myself. I mean thoughts of just wanting to jump off a third story balcony, but not consciously thinking "I want to die". These thoughts aren't "normal" and yes, when you learn coping skills you'll be able to fend them off easier, and you won't feel compelled to act on these thoughts.
I think you're experiencing what I like to refer to as "all or nothing thinking in the world of psychiatry and mental health" Don't feel bad, I've had professionals do it to me! What I mean is that you say "oh, well I'm functioning on XYZ level, so I must be ok" Well, the thing is that you don't have to be a complete basket case in order to have a mental health issue. Just because you can go out in society and appear just fine doesn't mean that everything IS fine.
Me? I can make myself look fabulous, I can act completely normal in public, and nobody knows I am dealing with PTSD. I even had a community mental health program kick me out, one of the reasons for kicking me out was because I looked too good. So yeah, I guess I try too hard? (Edited to add, I don't actually think I'm so fabulous, rather, I try REALLY hard to look my best so that I can hide all of the bad stuff. I'm probably overcompensating...)Anyway, the truth of the matter is that I have been declared completely and totally disabled by two separate government agencies, and my social security papers say "recovery not expected" If you casually met me in public, you'd be surprised to learn the truth. So my point is that yes, we can appear "fine" on many levels, but that doesn't mean that there isn't an issue, or that because we appear "fine" that we should just ignore other issues. It's not a matter of the good being able to outweigh the bad. You kind of need to deal with the bad as well.
