Wow, I'm sorry you're feeling this way and wish you all the best.
First and foremost, stop trading and investing into ICOs, if you're not that financially well of it's not going to end well - especially since your having some personal issues at the moment. Trading should only be done in a clear state of mind and if you can afford it. Even then I'd advise to just keep some money in Bitcoin and a large-cap coin, nothing small - but ONLY if you have the money and don't trade with it, just leave it and forget about it. This stuff isn't important man, don't stress over it.
Now, with your girlfriend, I really think you have to sit down with her and talk about how you're feeling and you're worried about the finances. If she likes you she'll definitely understand.
The key takeaways here are, be honest to her and to yourself. Don't spend money on ICOs or trading if you're struggling financially or mentally.
If you need someone to talk to, you can hit me up. Look after yourself mate, good luck with everything!
