i can't feel happy pls help

I'm sorry you are going through this and feeling this way. Life can be really tough and trying especially when we can't seem to find good enough reasons to hold on. Try doing the little things every day that make you happy, even if it's only for a little while, like taking a hot shower, a fresh cup of coffee, a chocolate snack, anything that can bring a little bit of positive in your life. The most important relationship is with yourself so be completely selfish and take the time to do the things that you enjoy. When you start to do things you like and enjoy then like minded people will come around you. If you are introverted or shy, try joining groups online, even Facebook groups. Commenting and interacting with other people who like the same things as you will help you start to feel better. Best of luck.
