How can I support my friend who is gay?

My advice would be to treat them like you normally would before you found out. Maybe ask them what they need. Also, the Trevor Project has a guide for how to be an ally.

Show him or her your compassion, and listen to one's thoughts. Offer your help, and make your support in general public if possible. Tell the person that he is always welcome to stay at your place if he needs it. Tell him that he should find a local community, or if not possible - go online. Or if he or she seems doing well, then treat them as everyone else, don't make any fuzz.

By being understanding of how they feel, and any stress they may receive because of their orientation.

Remind them that it doesn't change anything. That sexuality is a sliding scale and shouldn't be used as a defining factor of a personality.

You can support you gay friend by making him/her confortable arround you and deffend her/him everytime. acepting and care.. gay people are exactly like bi, pan, hetero so ....

Being an LGBTQ individual myself, I believe the most important thing is to let them know that you're there and accept them for who they are.

Simply saying "I support you" helps already a lot. Listen to them, if they need to tell somebody about their worries and hopes.

The most helpful and supportive thing you can do for them is just to be there for them, always listen to them and always offer support. Be open with them and try to let them know that there is nothing wrong with them. Having a good supportive friend can make all the difference in the world to someone.

Continue to be a loyal friend to them! This includes being open and willing to listen when they need to talk about something relating to their sexuality. Knowing that you will not judge them and that you'll be there for them is likely incredibly important to your friend. Stand by their side when they need you and back them up when they face struggles. You can also do your part to educate yourself on LGBTQA+ issues that you may be unaware of, which will help show your friend your commitment to understanding and respecting them.

I think that a large part of supporting an LGBTQ+ friend is a willingness to listen. While you may not be able to directly relate to the challenges that your friend is experiencing, offering him or her a source of support and understanding will go a long way. In addition, try your best to keep an open mind when talking to this friend. Many people in the world are going to try to bring him or her down with their prejudices, and your willingness to be open and caring whenever needed can really help.
