What major did your friend study? It is easy to find a job these days, but it is also hard to find one. When you start looking for a job, set a low threshold for yourself and don't ask for too much salary. First, learn the skills steadily, otherwise it will be difficult to find a job. Nowadays, work experience is required for every job, and it is difficult to move forward without work experience.
You said you want to give your girlfriend some gifts. I think a cartoon bouquet is a good gift. You can add a small card to the bouquet and write some encouraging words to cheer him up. He will definitely need your help.
Do you have any photos of him? It would be best if he had photos of him when he was full of energy. It is also a good choice to make a real doll with the photos at that time, so that she can see herself at that time and give her some confidence.
Or give him a mirror to let her see what she looks like now, let the mirror wake him up and illuminate the road ahead. Of course, there are many other gifts that can help him get out of this predicament, but I can only think of so many gifts now. If I find any better gifts in the future, I will add them.
I hope my suggestions can give you some inspiration.
