Feeling Overwhelmed and in Need of Guidance

Assalamu alaikum, I'm a young Muslim brother from Egypt. I'm dealing with some real struggles right now. I'm not happy with how I look, and I face some financial and health challenges too. Alhamdulillah, I make sure to pray on time, stay away from haram things, and I've been trying to read more Quran. But it's hard-sometimes I lie awake at night, asking Allah why I was made this way, and I just can't seem to accept myself. To be honest, it's gotten to a point where I feel like I might end up spending my life alone. What really scares me, though, is that I keep having thoughts about harming myself. I'm worried I might not be able to control these feelings. Has anyone been through something similar? How do you cope and find strength in your faith when things feel this dark?
