I never was good, but I am worse than I was before

It sucks. I keep losing games again and again and again. I lost before, but now it's like i am on a losing streak, and I realise I make so many stupid mistakes and I don't ever play any moves that I am proud of any more. 

Bloody hell... -.- I am not getting better, I am getting worse again.

Any tips on how I get back into it mentally? At this point I rather play plague inc than chess.

Get a book like Chernev's "Logical Chess." Find a quiet place and play through every game on your chess board. That will give you many ideas on how you can do better in your own games.

Hightides, I do the same. I have to take some time off to get off of my negative trend. Caused by my impatience. I lose focus and get filled with frustration. Time away helps me. But I can't give you any other concrete advice because I suck at this game. Good luck!
