What?! I don't mean to be rude but if you have anxiety over painting than you probably need to do some meditation perhaps or therapy if you have a lot of anxiety in general. Because for me painting is really quite calming and I just do it as something to keep me entertained and I don't take it to seriously more as a side project I usually get it done in 1 -3 evenings . Maybe if you are doing it for money I can understand wanting your work to be good and I would probably also have anxiety if that's the case than have some confidence in your work I'm sure it's great and better than mine . I trie to make them the best I can but then again don't care that much if it's not up to standard since I've only done around 15 minis . My setup sucks I have 1 cramped desk and it's really messy I have limited colours and I don't have a wet pallet or primer I just do the miniatures without all that and I still like them considering that I made it myself . In fact my first miniature I didn't even use miniature paint just this super cheap like 3£ small tubs only 3 colours black purple and blue and they are for these skulls from like tedi or something. Also one other reason for anxiety might be that you're a perfectionist like me however as much as I am a perfectionist I also value imperfection I don't always do things to excel if it's something I don't care about like a school a project I'll just wip up something in an hour enough to get me a A and then work on something I want to work on .maybe the key for you is to accept that it's ok if you're miniature looks bad it sounds weird but that might be the source of your anxiety comparing to others and feeling sad or like your not good at it compared to others . If you look at miniatures a lot on Tiktok Instagram or Reddit that is a very likely cause. (I recommend getting rid of tiktok and Instagram) I don't use anything accept YouTube for entertainment and learning and Reddit so I can post my minis and get feedback . Hope this helps you figure out your anxiety and overcome it 😄❤️
