How can I spend more time with my family when I'd rather be alone in my room all the time?

It's sometimes difficult to socialize especially when your room is a safe zone but I would just recommend at least interacting for half an hour, or watching a show before retreating back to the safety zone (your room).

Family that eats together, stays together. Have some lighthearted chat with your family members while dining together. That chat will open up New dimensions for you to spend more time with your family in coming days. Celebrate birthdays, anniversaries, festivals with your family. Small happy steps lead to big happy changes. Go on holidays with 'em. Travelling together is a really nice way to strengthen the family bond.

It is important to spend time with your family, as even though you may prefer to be by yourself, it doesn't feel good in the end! If you feel like you and your family have nothing in common, try to start a discussion about a common topic, for example TV shows or favourite films, this will help you to build a bond with your family and will make spending time with them more pleasurable for you, so you will want to spend more time with them than alone. However, if you feel like you need some time alone, do so, as long as you are not isolating yourself from others!

Just think of the outcome of spending time with family stronger bonds and more comfortable with them

I'm actually this way, and if you desire to spend more time then find an activity outside of the house for the family to do. That way, you have no choice.

Try to find some common interests. What do you like to do in your room? maybe you like watching movies, or playing games. Maybe plan a family game night, or family movie night. You could take turns picking the game or movie. You might like cooking, cook a meal for your family and eat it together, talk during the meal. The best way to spend more time with family is by talking. Just talk to your family and find some things you all like to do. Then do it! You will be growing closer everyday!

You can choose to be alone but don't forget that, loneliness can be shared with your family too. You can try that or just try to spend quality time with your family.

Its good to have an alone time once in a while, but too much of it is not good either. Try to allocate time for everything including your family.

Try to engage your family in something that interest you. Maybe suggest that you all do something fun that you and they would enjoy.

Maybe you can arrange activities that you like with your family, even if its just like watching a movie together.
