To be honest, it's best not to share your art if you want to avoid criticism. People generally don't care about how much effort you put in, and, intentional or not, most people are rather cruel with their criticism. Criticism is mostly useless, as well. People have given me crap for saying that before, but it's true. 99% of the people who look at your art can't do anything better, so all they can tell you is their opinion of it. If you set your work aside for a week or two and then look at it again, your own fresh opinion is just as useful as any random stranger's.
Now, if you get criticism from someone who is making things just like you want to make, then that is useful criticism. People who have reached a high level of ability tend to be much nicer about criticism anyway - they know how long it takes to achieve something decent.
If you want to be safe, only post the art you aren't in love with. That way, when people tear it apart, you won't feel bad about it. Another way to stay safe is to create an immense amount of art. This is something I've been trying to work on, actually. Don't spend 10 hours on a drawing, spend 10 minutes and move on. This will force you to treat your work as less precious.
The real prize to go after is the ability to draw quickly. Go draw 10 figures from reference in 30 mins, and then 10 figures from memory in 30 mins. When that's done, you will be making quick, confident lines, and this is what makes an impression on people. Look at adventure time - there's nothing particularly realistic or even well structured about the drawings. It's just that they're drawn with a confident hand so they don't seem "wrong" in any way. (Not implying anything about your work, here. Just an example.)
Anyway, I can relate. People suck. My mom was never very nice about my art either. Best to just forget about other people. Whenever you feel upset about something someone said, just let go of it, forget about it, think about something else. It's not very important what other people say anyway.

Thanks for the tag,mam.While I'm not wise enough to give anyone any advice on this 'heavy' subject,I'll just do my best to put my thoughts into words here.And I'm glad that people here had been giving you advice and support you need.
I'm sure most,if not every artist has faced some kind of fear or doubt when they put out their work for the public to see but that's just the reality of it.It isn't easy to get over this problem as it's something that feels like it won't go away but sometimes all it needs is a different perspective.From what you wrote,you've been through some rough times;your parents are harsh in the way they deal with your work but maybe there's more to the picture,something behind all their rather crude treatment of your hard work.Did you try talking to them about it to find out why they don't like it?Is it because they aren't art lovers?Or if they are,was it that your work didn't meet their expectations?I can almost feel your pain there,the closest people who you thought you could turn to for some encouragement ends up doing the opposite-crushing you,your enthusiasm for your craft,childhood dreams,hopes,leaving you confused and hurt.
Sadly,it's the same with the world where you show your works to but at least,those who would love to crush others works and confidence are only a minority.These are people who just pick any fault,no matter how insignificant,in any work and with today's technology,they will make it look like it's a big deal.Artists,past,present and future had,have and will have this problem.no matter what,because it's what makes us humans.Back to the point,you're right to say that 'sharing anything with others is bound to bring pain' but it's more than just pain,there'll be support from like minded individuals who might have been in your shoes or worst and who knows,when these people see your work,they'll be encouraged to start their journeys.I mean,most,of not all successful people have been inspired by others,so why not be the same?If you love what you do and you also know it's going to be a struggle,set your mind to it,grind your teeth and just press on and be the light to others like you.You also know that doing what you love also has to involve 'green' rewards and that would mean getting hired by someone or company but let's suppose you're still uncomfortable with putting your work,there's a few ways to still get noticed and maybe a job.One is to have friends working in the industry you're aiming for and you can impress them with what you can do and if you're capable enough,you can be get recommended for a position there.Another method is to 'open' yourself and let your works be noticed.That means creating and sharing your works in portfolios on websites with communities of people who share the same interest with you.This is not easy to do,based on the problems you wrote above but it all still depends on you.If you want to have a future working in a music/art industry,then being open to the world outside would mostly be the option to get there.
That's all I can think of for now,but thanks for tagging me,though personally,I'm not the kind of person one would turn to for advice,so pardon me if any point I brought up may be flawed in any way.I'll be happy to get your reply and thank you for your time!
