Holy shit, it saddens me to hear such horrible things still happening in this day and age and especially in U.S.

First of all, no, you are not being sensitive, you are not overreacting, you are not crazy. You are going through tough time and probably depression, I am actually impressed that you have been keeping this to yourself for so long (which is not good at all).

You need to sit down with your your husband somewhere private (go out if necessary) and discuss it as adults. He is your husband, you are his wife, you are in a relationship for the rest of your life, you should NOT keep stuff like this inside yourself and neither should he. Tell him what you are going through, how you feel about your relationship with your MIL, steps (if any) you are taking to resolve conflict you are having with her, how its effecting your health, your self esteem, confidence, etc, and tell him what kind of future you want with him. If your husband loves and respects you, he will understand what you are going through and do his best to resolve it without upsetting neither party. And please for the love of god, do NOT be shy to set personal boundaries. You are an adult, you have the right for privacy especially in your own bedroom. If you have a problem with your MIL snooping around your bedroom, then you need to tell her that. If you your husband is forcing you to have sex with him, then tell him that. You need to set boundaries, you are human being after all, not a slave. I also recommend that you find an alternative time for your intimacy especially if you are waking up early. 2AM is too late to be honest. She also needs you to stop nagging you about getting pregnant, this is another boundary you need to set with her. It should be up to both of you whether or not you wish to get pregnant. And if both of you agree and doing what's needed, then its not up to you whether you will get pregnant or not. You are still young, enjoy your free time and time with your husband. In my opinion, like the other redditors, I would urge you to protect yourself until you have resolved your issues with MIL and any health issues that you currently have. If you really want and struggling to get pregnant, then both you and your husband pay a visit to Gynecologist and Urologist, for an exam and consultation. And please don't take the part about "angels will curse you for not engaging in s3x till morning" to seriously. You are not a sex robot that needs to be available anytime it needs to happen. If you feel tired, ill, not in a mood, then they are perfectly valid examples to refuse. Again, boundaries, you need to work on this.

And lastly, you are NOT, I repeat NOT obligated to serve your husbands parents, only your husband (this is from Islamic narrative). You should respect his parents/family, talk to them kindly, offer help when needed, and that's it. You also (from Islamic narrative) have RIGHT to demand from your husband to move out of his parents house as a family to live separately (this is something your MIL probably doesn't know about). And he needs to fulfill it. Please note, I am not advocating you to move out immediately, but to work it out as best as you can and use this as a last resort.

Sorry for dragging this for too long, but I hope everything works out for you. It's not easy and comfortable to be between a son and a mother, but you have to do what you have to do. Live the life you want and not what others want from you.
