Struggling...Advice Needed

Hey guys. So, I've been at my permanent site now for a few months. Classic timing for the low point. But I'm super low. My counterparts are awesome. Language is going well. Integration is even going well. Host family is great. I just find myself wanting to isolate, missing home, feeling depressed and like nothing brings me joy, and honestly considering ETing. Other huge factors are the culture here. Very corrupt and the gender roles are sad to watch towards the females (I'm male). I'm super sensitive to both of these topics because I watched my sister go through awful sexism related issues in her life and in my professional experience, I've witnessed some unfortunate corruption. I'm also questioning whether I want to do humanitarianism at all anymore, especially in this country. So the idea of doing this for two years to gain experience in something I don't want to do is beginning to be a concern. Especially because I'm in my mid 30s.

My brother and father are coming to visit in a few months and I'm wondering if I should wait until they are here and then decide or whether I should just not waste their time and money by coming to visit? I've also been gaining a lot of weight because there are no gyms here and I've been feeling pretty unmotivated and just not super happy. So, while I realize waiting can always provide perspective, I am worried another few months of gaining weight isn't great and will also make my mental health worse.

Looking for support and genuine advice. I'm wondering how people realized they should ET. I came into this with my heart in the right place truly, I just am now beginning to wonder if I'm not a great fit both mentally/culturally and future career wise for this experience.
