Would love to help someone solve their mind related issues.

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 an 18 yrs old female. I want to have a real relationship, but everytime i get the chance the same thing happens. We hang out for a bit, every thing is great we get to know each other and all that gooey mushy stuff, then as soon as we have sex I lose interest in the guy. and its not like the sex is horrible i mean there was one or two times but most of the time its f-ing great. regardless i lose interest and then i want nothing to do with the guy. sometimes we try and be friends but it just becomes awkward. whats wrong with me?? i try to have feelings but they are none exsitent, why is tht? i am not a promiscous person at all, I havent had sex in forever because of this (6 months and counting).Its hard for me to actually express my feelings. My ex told me i was a robot cold and emotionless. i would just like some opinions on this whole situation. I discussed this with some close friends and they tld me i should see a therapist because i might be a psychopath.

you see, I've liked him for some time now but never went for it cause I used to think he was weird. (attractive though) but for the past few months him and I have been really talking. & he told me he has ASPD which I've now been researching a lot because I genuinely care for him and want to make sure he's like you know, okay?
I can't tell if he likes me or not or if we're going anywhere though? I've expressed to him many times how I like him and he thinks its odd/weird? is that bad? He let me take his V-Card but then afterwards said it felt like it didn't even happen because he doesn't really have "emotions". I'm so confused, he says he likes being with me and cuddling with me and he wants to see me like every chance he can & he blows up my phone when he gets on break/wakes up before I do or if I'm not messaging back. he's not mean or rude, he's not addicted to drugs. the only thing about him is he acts sort of emotionless like he doesn't like expressing his feelings/getting emotional? and he doesn't like kissing either which is weird cause most guys his age (19) do you know?
I really am so confused and I think I'm falling in love with him, he's the first guy I've liked since my last relationship which was a year & took a lot of healing time so I'm afraid.. should I keep going and see where it goes without getting my hopes up? or does it sound like I should just give up..? (I rather not) but I'd like to hear opinions from others with ASPD and your feelings about love.. have you ever been in love or felt strongly about someone?

What am i if I like watching a black man have not just my gf, but want to watch black men with anypetite white female, but lately my fantasies have been about watching big black men with young white girls that are 7-10. This is a uncommon fetish. Some one tell me what this would be called. If I had a label I could get help of understanding why I have this fantasy and try to control it. Don't like it because I have Shane a guilty feelings after I masterbate.
