Speaking of which, we've had a bare wall in our bedroom for about 13 months because I can't wallpaper and we're waiting for my partners step dad to come over and do it for us. She wants three painted walls but wallpaper behind the bed. I'd be sound with just paint all round, even temporarily but sound ok- whatever. But only once it's up can we put up the shelves which he was also going to put up for us. I've wanted to have some shelves put up for ages so I can keep my vape stuff, wallet, phone, keys, tv remotes, aerosols, books, anything I wouldn't want a 2 year old or a 4 year old getting their hands on basically. So stuff is safe from ruin or being lost and I'm not stressed out trying to find my car keys etc. I spent £90 on 3 sets of matching shelves about 12 months ago and they were just in a cupboard till recently.
Anyway, during this lockdown I had enough and snapped. I eventually dug out all of the tools my Dad left me from the shed and set about doing it myself. While not perfect by any means I've got two up on my side of the bed and one on hers and it was surprisingly easier than I expected (I'm not sure why I thought it would be so difficult really). It's still really rewarding now to walk into the room and see everything up there all neat. Feels really rewarding to do it yourself.
Doesn't help your situation, but still, defo look into doing things yourself. Youtube is such a help as well.
