5'4 less than 100lbs. help?

Make sure all meals have a good source of protein carbohydrates and fats. Examples; Breakfeast: Boiled eggs, two slices of whole grain toast and glass of milk. Lunch; Breast of chicken with rice or potatoes. Dinner; Chicken/Steak/Salmon/ with Rice/Sweet Potatoe/Potatoes and some veg.
Try and have a glass of full fat milk after every meal to get in more calories.
Also snack between meals with nuts, whole grain toast,peanut butter.
A lot about bulking is about making foods that you will like so get handy in the kitchen with adding herbs and spices to add flavour.
Gradually start eating a small bit more everyday and your stomach will get used to the amount of food your eating. What's happened is your stomach has shrank due to being used to small amounts of food but this will change after a week of so eating gradually.
Hope any bit of this info helps. I'm on my own journey of gaining weight and getting there gradually.
Goodluck

Just eat the foods you like and try for a small surplus of calories per day over maintenance. Generally, we recommend 250 to 500 calories per day over your maintenance so you need to figure out how many calories you need then add in some extras. It's not really that hard to gain weight but it's often more the willingness to do it that stops people.

Wheelhouse is on the money with foods that you like. I've found that getting the non-diet and non-light versions of foods (especially your faves) is super helpful. And in the end, my mantra is any calorie is better than no calories at all after I had many long months of less than 500-700 per day. So no feeling guilty if you reach for ice cream and goodies! Just remember to try and add in healthier calories when you can, like cooking with olive oil, eating nuts and nut products, snacking frequently, etc. Good luck! And I hope you make good some progress that makes you feel better

Eat more dense foods; avocado, peanut butter, nuts, eggs, full fst dairy, red meat, ice cream, bagels, drink calories (more chocolate milk), high calorie protein bars or shakes, add oils and dressings to foods, lots of cheese.

Go buy some all natural peanut butter and some crackers and eat.
Do not use this place. Therapists warn people that these sites are harmful for those trying to gain weight. Do not weigh or measure food.

I think you are referring to people with EDs, correct? I think you maybe presumptuous since the OP hasn't mentioned this.

Also don't know why they'd be here is they think it's dangerous

It's certainly not dangerous for people without medical conditions (including EDs) to seek advice in such forums as this. Those who are suspected of of having an active ED or of being pro anna are often asked to leave these forums for their own health and well being.
