Is it wrong to ask Allah to take my soul when I'm overwhelmed?

Assalamu alaikum. Lately, everything feels so heavy, and I've been asking Allah to just let me leave this world. I know it might sound bad, but the thought brings me some peace. Since my father passed away, I've lost all sense of safety. I don't want to study, I don't want to think about a husband-I just feel completely drained. I've been crying myself to sleep for two months, and it doesn't seem to get better. I'm an emotional person, I cry easily and feel scared by everything. The one man I relied on as a child is gone, and I can't lean on a husband now because I have to be independent in case things don't work out. But with my anxiety and poor grades, I feel incapable of that too. I just want to rest, I don't want anything from this dunya anymore. I want this life to end because I can't bear feeling so unsafe and insecure anymore.
