I know this may seem ridiculous

I tend to jump into things, I've been seriously depressed for the majority of my life and I'm finally getting out of that, I discovered I was half decent at something and went out and bought an expensive MacBook, I can't use it, it's different, I can't use the software I actually bought it for (there did no learning) and I've wasted my money. I can't get a refund and I feel so stupid and so low. I hate that I think things will make me happy just for them to make me hate myself.
