Stretch mark crisis

Does anyone know how to get rid of stretch marks? I’ve been use to them since I went through puberty and gained a lot of weight I eventually got on a healthy diet and regular exercise that kept me around the same weight all throughout High School so I really never got anymore after that. But when started college I stopped working out and lost all my muscle I had built! Now that I’m back on track and lifting again I’m getting these awful stretch marks that drive me crazy! They sometimes itch so much and I have them all on the sides of my thighs and tummy so I really go crazy itching!
