I carry around a little pocket knife , when its just me and my daughter home. I won't take a nap when my daughter is sleeping aswell because I'm scared someone might take her while im sleeping or threaten to hurt her to make me do things. My mind continuously comes up with bad situations (example-if someone is knocking at the door I get paranoid they might force there way inside and hurt me or my family so ignore it but then I think if I ignore it they might think no ones home and break in ). I feel safe when my partner and everyone is home, but when its bedtime I lay awake and feel like someone's watching me from the windows or is going to break In and kill all of us. When I dose off I wake up scared when I feel my partner is gone and I jump to conclusions he has been dragged away and stabbed but in reality he just goes to the toilet a lot during the night . I usually end up grabbing a knife and putting it safely near me till I finally fall asleep which normally is around 3 in the morning. I feel it's my job to protect my family and if I let my guard down, someone will take their life's away and mine. I try to talk to my partner about it but he just says "stop thinking silly", I'm trying to stop but its not easy. Am I just to paranoid or crazy...

So i've never written a post ever on any forum, ever, and since things have changed for me recently, i'd decide to give this a go. Might not come back to this but i want to get whats in my head out there and see if anyone has anything to say about me and my problems.
My problems: I care about my family too much. I'm almost certain that I have depression, mild anxiety and a myriad of other mental health problems but I've never been properly diagnosed because I care about my family too much to have them worry about me at all. I also come from a culture where mental health is not a 'real' problem, but rather a thing for the weak or the bored.
I think about death a lot BUT i'm not suicidal. I'm fine with death and i'm not scared of it but I would never be able to go through with it as long as my parents are alive because I can't put them through all that pain. If they died though, I would have not much of a reason to keep going, but that is not the point of this post.
I've always been very aware of my issues and i've always been able to talk myself down in my head like there was a third person that tells the two conflicting voices in my head what to do. This third voice sounds like a trusty friend, insightful parent, or even a advising counsellor, when i think about it. This voice knows what people views as normal and suppresses my arguing voices to make me seem 'normal'. It usually takes effort but I know it works because everyone thinks I'm still this smiley, happy girl, which really hasn't been the case since about 7 years ago (when my first encounter of death in the family happened)
My dog (who's been with me for almost 15 years) died yesterday and I was sad but it wasn't a fearful, regretful sadness. It was more of a "i'll miss you" and "we've spent good time together" happy sadness, though it was really sudden and shocking. I still miss him but I don't think I'm doing too bad. My parents on the other hand haven't been able to sleep, eat, not spontaneously cry, and not talk about morbidity every couple of hours. They also hug me a lot because they think its comforting for me, and probably themselves too.
I guess what I'm saying is that is it weird that I'm so aware of what I'm almost sure I have? Does this mean I don't have these mental health issues because it doesn't really affect my daily life and I know what triggers it, how to control it, and what works/doesn't work? Do other people with mental health issues experience this too?
An analogy (if you're still reading): I deal with my problems like dealing with my period. When it starts, I know what I can do to not let it leak out for the world to see. I know what the best way to deal with the dirty pad/tampon is, to chuck it out (feeling all my feelings/non-feelings but in a physical location where no one will see me then throw them out or at least leave them where they can't be seen). I clean up after myself and flush the bloody mess away (make sure no one can physically see or pick out that I have problems at any point of any time)
What do you think?

i am 23 year old and doing a job as a designer.
now a days my feelings is very dirty and i start doing fantasy about dirty things.
i can't explain what should i do now ?

i am CONSTANTLY picking off scabs and pimples on my face and even more so on my back. it's so embarrassing because i have tons of scars on my back and luckily on my face it isn't so bad. but whenever a new pimple or scab appears i pick it right away. i don't know why i do it. i don't even think about it when i am doing it. i don't have any disorders so i don't know if this is one and i want to know if i may have something that needs to be checked out.

I've been looking everywhere online for advice, and everyone I talk to says I should go to some sort of psychotherapy. I don't know about it, though.. I finally had the courage to tell my sister what's been going on - I've been hallucinating, I can't sleep too well (3 hours a night is my current average), I get very nauseated whenever I eat so I've lost a significant amount of weight. There's headaches, dizziness, fear (of nothing, really), anxiety, trembling, it's hard to breathe sometimes, too. I had a panic attack about two weeks ago, it lasted for maybe fifteen minutes. My dad says he used to have panic attacks, and I read somewhere that it's more likely for me if it runs in the family. I can't stand being alone because these hallucinations get worse when I am. I'm also being cold(-hearted) lately towards my mom and sister. I feel very anxious -at night especially- and self harm calms me down. I started scratching my wrists and digging my nails into them. I don't want to do this, but it's become very addicting and even soothing. My sister wants me to see a psychiatrist, and put me on anti- depressants. What should I do about this? Please help.
