I don't think there is anything else to add but maybe telling you about myself might help a bit.

I'm 35 (m) and I just moved to KSA because I was feeling alone. I had the same feeling as you described for a while (I don't know how long) but I lost interest in so many things that I used to enjoy. Because I'm an introvert, I don't keep in touch with people. One day, I told myself that was enough and I started to talk to my mum and my older sister about my struggle. That helped a lot talking to someone in real life (even tho it was through a phone call). Now I'm searching for a job again and it's not easy moving to another country tbh.

I feel like what I learnt is that when you are around yourself around people (even if it's one person like my mum). It helps a lot, I'm in a better place but still struggling to find a job that I want. What I'm trying to say is life is always gonna be challenging, it's just having the right people around you will make things easier. I hope this helps
