I [21 M] want my girlfriend [19 F] of 4 months to go to therapy, but she says she doesn't need to / is afraid.

My girlfriend has never felt great about herself, even since she was little. She's always felt like she's not good at anything, has gone through periods of intense self-hate, and self harmed for several years, which finally stopped about a year ago. Basically, she has had almost no feeling of self worth for as long as she can remember.

But she's been a lot happier since we started dating. And so have I! Our relationship is pretty great. We talk about everything, we're honest with each other, we help each other with whatever we're going through, and so on.

The thing is, though she feels a bit better about herself now, it's not yet in the 'good' range. If she messes anything up, she says she's the worst and how could she be so stupid and everyone else is better than her... I try to help as best I can - I tell her I love her and specific things I love about her and she's not stupid and she's not the worst and all the things I can think of to say - but it only helps so much. She trusts that I'm not lying when I say these things but she can't get herself to believe it.

I wish I could help more, especially when she believes it's all her fault and such.... but I'm not a psychologist or therapist (and I don't try to be) so all I can do is give my best loving support and try to reassure her that it's not her fault and she is good at the things she does and such. But it only helps so much.

So I asked if she wants to go talk to someone who can actually help with all this, but she says her problems are just little problems, she can handle them on her own, it's not a problem, there are more important problems for therapists to deal with, or something like that. She's actually very honest with herself, except when it comes to getting real help with all this. I don't want to push her or anything, but I don't know what else I can do to help. I just want her to be happy with herself.

So, what I can I do to either help her get professional help, or help her get better myself?

Also, I've talked to her about this a lot and showed her all that I wrote here and she agrees and wants to hear any advice on this as well.

tl;dr: My girlfriend has very little self worth, I think she should get professional help, but she doesn't think her problems are worth it.
