Feeling a Bit Lost and Let Down Lately...

Assalamu alaikum, everyone. Lately, I've been putting in a lot of effort, but it seems like nothing is turning out the way I hoped. It feels like I end up disappointed by people in the end, and my friendships don't feel very deep. After some recent tough times I went through, I think I've become a bit more closed off and hard-hearted. My mind keeps saying, 'That's how you were treated, so don't get too emotionally attached to anyone.' Because of this, I struggle to connect with people on an emotional level, and it honestly makes me feel bad because I used to be someone people enjoyed being around. And it's not just about people-it feels like everything is going sideways. I feel stuck and unsure how to move forward. If anyone has advice for when it feels like everything is slipping away and nothing is going your way, I'd really appreciate it. For context, I do try to pray all my salah (though I miss Fajr more often than I should). Please keep me in your duas. Jazakum Allahu khayran.
