You are full of good ideas! I was thinking of buying a big box and putting everything in it because I'm not prepared to throw them away just yet and then hiding it in my parent's room! I can't really imagine myself using the gifts so perhaps I should donate them because a lot of them are pretty expensive and maybe someone else will get some enjoyment from them?
@Hope96, I've seen your posts and am worried about you. I hope you don't mind me making a couple of recommendations? These come from a feeling of truly wanting to help, but please feel free to ignore me if I'm annoying.
Have you tried drinking cherry juice with dinner? That can help with sleep - as can melatonin supplements, which you should be able to buy over the counter (without prescription). Otherwise, perhaps consider seeing a doctor and getting a limited-time prescription for sleeping pills ... the only hesitation I have in recommending this option is that most of them are incredibly addictive and hard to break free from (some will even leave you with a hangover-type feeling in the morning).
Also, based on what you've said about your ex's things being in your room, I think that might play a huge part in the way you're feeling. I think donating the gifts would be an excellent idea ... if you were to put them in a box within your house, you'd *probably* still think about them. I'm very hippy, woo-woo-ish, but I think you need to shift the energy in your room ... buy some white sage incense and wand it around the room as if you're conducting an orchestra. Wash your curtains / blinds (or replace them), shampoo your curtains and rugs (or replace them), give the walls a fresh coat of paint (if you're able to), change up your duvet cover / bedspread. Pinterest has great ideas for dreamy bedrooms. By doing these things, you will introduce new energy into the room which will help greatly, I'm sure.
