Mental health and crypto

I know that it's a big world and others are likely in worse positions than myself, but my mental health has been suffering greatly since I started in crypto. I invested in December of 2020 and saw incredible returns, I eventually even accumulated 0.65 BTC, which is the most money I've ever had in my life. Fast forward to now and failed trade after failed trade has left me with barely anything left. I feel sick all the time knowing if I had just held I may have soon had a life changing amount of money, the type of money that could have changed absolutely everything for me.

I have no one to blame but myself and it's been a hard lesson. I can't stop thinking about it. I feel so stupid.
