I feel like giving up

Don't give up man. The storm is fierce and it can feel like it will never end but remember every storm will end. As Number said, on the other side you will be stronger, and generally wiser.
You will be able to look back on this storm and next time life throws one your way you can remember that you got through the last storm.

Look for the positives in your life as well, don't focus on the negatives because negativity breathes negativity and will pull you down further.

If people patronise you.... Screw them. They haven't taken the time to know you and they aren't worth your worry or thinking time. People like that are best left forgotten.

I remember that overall, life is not as bad as it could be. I live in a pretty good time to be alive. I have a pretty nice place to live in. I have a decent job. I have my health more less.

The biggest loss in my life so far has been my sister. I try not to focus on that, I focus on the good stuff. 

I find things to be grateful for and appreciative of. If I were to look for things I don't have, that would depress me, so I focus on what I do.

To help fight depression as well, I've found from my own experience it's great to have goals. Social goals, professional goals, educational goals, goals in my hobbies and more. Whatever goals appeal to you. These keep me driven and constantly learning more/doing more.

And keeping busy and distracted is good. It keeps you moving, breathing, and it fights against depression and anxiety.

I also find writing down what's upsetting me helps a lot. Write it down and ask yourself what you would say to a close friend/family member who said the same thing to you.

Keep the faith man, hold on to that hope and know you are not alone in how you are feeling.

Some good ideas there, thank you for sharing. Sorry about your sister. I will try to keep the faith. There must be good in humanity. We evolved from beasts that only know how to hunt and kill one another, so there must be something
