How do you recover from a wallet drain

I had $30,000 worth of BTC that i worked my ass of to get to . it took me 2 years of saving up to get there . about 3 months ago my wallet got drained of all my BTC . my BTC was kept on my phantom wallet . I know Im stupid for not storing on a cold wallet but how does this even happen . I never connected my wallet to any apps , I never gave my seed phrase to anyone and I never interacted with any suspicious links . my questions is how do u mentally and finically recover from something like this . my mental health has been stuffed since this happend and it still dosent feel real . I know I’m not the first person this has happend to and I won’t be the last but this is genuinely such a shit feeling . cops said they can’t do much . this really sucks .
