Loren, I'm sorry things are difficult right now.
Have you thought about changing the behaviours that have upset your girlfriend? I mean, it sounds like she's mostly upset because you've neglected her, which makes sense.
I've been on the other side before, the one being neglected, and up until a point I think it can be un-done. If you realise what she means to you, I think you can work at showing her. She probably has an idea that you don't really care about her, because you don't seem to want to spend time with her.
I do think if you probably need to have a long talk with Morgan, let each others feelings out there, see what each of you needs and expects... and maybe then it will be easier for both of you to know what you need to do. What the other needs.

It would probably benefit you to talk to a doctor or a therapist. I'm in the UK so I don't know about fees but, is it free to see a doctor? If not I understand it's not easy for you. I'm glad you're here and talking about how you feel, it's important to let it out, don't keep it in and to yourself.

If you are feeling suicidal it's ok to admit that you need help. Like the byzantine said there are helplines, maybe that would be an option for you if you can't get therapy right now.
