I have been considering picking up my guitar again and maybe persuing my dream of music again since I put it on the backburner
Yes, do that. That is what "Get a life" is all about. i.e. Doing things for you that make YOU happy and take your mind off... well you know who.
Other than that you have received 100% pure golden advice from robx, PDT and SMQ. Follow it to the letter no matter how "counter-intuitive" it is and you'll find yourself crawling out of this hole a lot sooner.
All the best.
