Tired of being broke

My family was always poor, my parents divorced early and went seperate ways, I never got a college degree. I am a 33 year old who has had to work and pay for rent since I was 19 years. I had a breakdown at around 27 due to a bad breakup, depression, alcohol and drugs when I blew through all my savings.

I got back on my feet, got some savings over these last years and I am now constantly working overtime to put some aside and studying at night in hopes of a better wage in the future. But always paying stupidly high rent that is getting higher. Now I have around 7k euros and the inflation is destroying my savings... I cant buy a house still, and my old car will die eventually. I have been reading a lot about finance and investments lately, acompanying markets, basically trying to make sense of it all. I put some money in low risk investment funds, and see where it goes, but it will never give me much.

Then there is Bitcoin. I do not understand a lot of it, but I have been studying its history. I read somewhere, when BC was around 18k usd, this guy saying that the worst that can happen if you put 1000 dollars in BC is lose most of it, and the best case scenario is earning enough to change your life. That kinda stuck to my mind, and Ive been holding myself from putting a good chunk of my savings in BC. I mean, Im not buying me a house, travel much or get a new car as I am right now, but I can still eat and have a roof over my head without my savings. Im just scared that in the future Im gonna need the money I lost in a bad investment.

I guess I iust need to hear someone say "Do it"

Edit: Your replies gave me a lot to chew on! Thank you guys for all your advice.

After re-reading my post it does feel like a downer! I am not THAT miserable! I mean, I dont have much, but Im healthy, have friends, I dont actually hate my job, I live pretty comfortable with what I have, and if Im not better, its mostly because I did not seek other opportunities out there because I do love the city I live in (Évora, Portugal), even if it's expensive af. I just wish I could have more, or could see a brighter future ahead of me, without so much uncertainty.

Anyway, I do have a sort of a plan, and I appreciate the insight you guys gave me, because I kinda got what I was looking for with this post, some hope and encouragement!!
