Scared of not being good enough.
I feel that most of the time I'm a burden to my significant other because I've had bad experiences in the past that traumatizes me still. I don't want him to feel like he's in a relationship with someone who doesn't care. In all honesty, I have a hard time conveying feelings and acts of love because I don't actually know what to do, and I'm highly uncomfortable with touching and talking to people for more than a couple of seconds. I want to love him, but I'm also battling inner demons which makes me feel like I'm a worthless being, not good enough for him.

Yep, a lot of people with traumatic experiences feel that way. It might help to think about what you would tell or think of someone else in your situation - would you think they don't deserve love because they're struggling? Another thing, have you discussed your concerns with your significant other? Does he understand that you do care and try, and can he reassure you?
